Peliin oli tarkoitus luoda ilmainen ja premium- versio battle pass -kaudesta erilaisilla palkinnoilla. Kehitystyötä edeltävä teo- reettinen viitekehys rakennettiin tutkimalla projektin kannalta tärkeitä aiheita. Opinnäytteen teoriaosuuteen hankittu aineisto yhdistelee kvantitatiivista ja kvalitatiivista tutkimusta. Teoriaosuus käsittelee muun muassa mobiilipelien syntyä ja nykytilaa, battle pass -käsitettä, tietokantoja ja kehitystyön työkaluja. Kehitystyön työskentelyn metodina toimi ketterä iteratiivinen ohjelmistokehitys, joka koostui enimmäkseen JSON-tietokantaohjelmoinnista ja pelitestauksesta. JSON-dokumentit lisättiin Nitro Gamesin kehitystietokantaan Heroes of War- land -pelille. Kehitystyön lopullisena tuotteena syntyi pelattava uusi kausi Heroes of War- land -pelin battle pass -ominaisuuteen. Nitro Gamesin henkilöstö oli ohjelmoi- nut pelin ja battle passin front end -puolen. Kehitystyö mahdollisti toisten ohjel- moijien kopioida kolmanen batte pass -kauden pelin kehitysversiosta live -ver- sioon. Lopuksi premium battle pass -tuotteen pystyi ostamaan pelin sisällä iOS App Store- ja Google Play -palveluiden kautta.

The purpose was to create free and premium versions of the battle pass season with different rewards. The thesis utilized both quantitative and qualitative research methods. The theoretical framework primarily consisted of examining the emergence and current state of mobile games, the battle pass concept, databases, and tools used in the development of online video games. In this study, the develop- ment method was agile iterative software development, consisting mostly of JSON database programming and game testing. The JSON documents were inserted into the development database of Heroes of Warland made by Nitro Games. The final product of this thesis study was a playable new season for the He- roes of Warland-battle pass. The front end of the game and battle pass had been programmed by Nitro Games staff, and the outcome of this study al- lowed other programmers to copy season 3 from the development version to the live version of the game. Also, it made the premium battle pass available for in-game purchase through iOS App Store and Google Play services.

  • Loot Boxes in Video Games - Call for Evidence
    Loot Boxes in Video Games - Call for Evidence The Gambling Health Alliance (GHA) is a coalition of 50 organisations and individuals with a shared interest in reducing the damage caused to health and wellbeing from gambling. The secretariat is provided by the Royal Society for Public Health (RSPH). The objective of the Alliance is to support policy-making to address the social, economic and cultural factors that contribute to gambling harm and the inequalities in health caused by it. We do this by highlighting gambling-related harm, engaging with policy makers, and promoting evidence that can be translated into reducing gambling harms. We welcome the Government’s plans to make the UK the safest place to be online in the world, and believe that tackling problems linked to loot boxes in video games would make a major contribution. We are therefore very pleased to respond to this consultation, and alongside our response we will be launching a campaign, ‘#LidOnLoots’, calling for loot boxes to be classed as a form of gambling. The campaign has been developed following discussion with our members who have agreed that loot boxes are a major problem and should be the focus of the GHA’s work. This response is primarily based upon data from the 2019 RSPH report Skins in the Game; research was conducted from November 2018 to November 2019 through six in-depth focus groups with young people held in England, Scotland and Wales, followed by an online survey of 1,025 11-24 year olds (from here referred to as ‘RSPH research’).

    THE DOTA 2 BATTLE PASS 1 The Dota 2 Battle Pass: prevalence, consumption, and attitudes of a player community towards a growing type of video game monetisation. Elena Petrovskaya and David Zendle, Department of Computer Science, University of York, York, United Kingdom. Author Note Correspondence concerning this article should be addressed to Elena Petrovskaya, email: [email protected]; telephone: +447817801339; address: Empire House, New Road, London, E1 1HH. THE DOTA 2 BATTLE PASS 2 Abstract As the profit model in the video game industry shifts from upfront payment to continuous exposure to in-game microtransactions, new forms of monetisation are on the rise. One such example is battle passes: time-limited content which provides players with an opportunity to access rewards not available within the main body of the game. In this paper, we apply a mixed- methods approach to conduct an in-depth examination of the Battle Pass feature in Dota 2. We consider 1) quantitatively, the prevalence of the Battle Pass within the Dota 2 player community, and 2) qualitatively, player attitudes towards this feature. Quantitative findings show that, despite the rising profitability of the Battle Pass, its presence has minimal effect on player uptake in Dota 2. Qualitative findings indicate complex player attitudes in which positive views on the Battle Pass contrast with concerns over elitism and difficulty in achieving rewards without spending money. Keywords: microtransactions, in-game purchases, video games, esports, battle passes. THE DOTA 2 BATTLE PASS 3 Introduction Video game monetisation is undergoing a shift. Video game publishers historically treated individual games as marketable products, and made profits from the sale of copies of these games themselves (Lizardi, 2012).

  • Fortnite: Everything You Need to Know About the Online Game
    Fortnite: everything you need to know about the online game The craze for Fortnite, especially its multiplayer standalone mode Fortnite Battle Royale, has exploded recently especially amongst children. So, what do you need to know about the video-game of the moment? Peter Yates answers the important questions. What is Fortnite and how do you play it? Fortnite, which is published by Epic games, is a game where players work collaboratively to survive in an open-world environment, involving combat against other characters controlled by the game or other people. Its gameplay involves cartoonish violence and characters that might be disturbing to younger players. The single-player or co-operative mode (played with friends) involves fighting off zombie-like creatures. Fortnite’s most popular mode is its standalone free-to-play multiplayer platform, Fortnite Battle Royale. This sees up to 100 players enter an online game, competing individually or as part of squads of up to four, to be the last player standing within a constantly decreasing battle arena. Fortnite requires players to create an account in order to play. Children will be required to give an email address, which they will subsequently have to verify, and a username. Why is Fortnite so popular? There are several reasons why Fortnite, and particularly Fortnite Battle Royale, have become 2018’s big gaming craze. Fortnite is free and widely available on Playstation 4, Nintendo Switch, XBox One, PC, Mac, iOS and some Android devices, meaning it could hardly be more accessible for children. The gameplay is simple but extremely immersive. Multiplayer games last up to 30 minutes, and players can quickly re-enter a new game, making long sessions extremely easy.

  • FTC Video Game Loot Box Workshop
    FTC Video Game Loot Box Workshop STAFF PERSPECTIVE | AUGUST 2020 Introduction On August 7, 2019, the Federal Trade Commission (“FTC”) hosted a workshop in Washington, DC on video game loot boxes and related microtransactions.1 In recent years, video game loot boxes have been the subject of national and international scrutiny due to concerns that they promote compulsive or gambling-like behavior or use predatory tactics to encourage addictive consumer spending, particularly in children. A number of countries have examined whether to regulate loot boxes, with some offering policy recommendations, implementing restrictions, or imposing bans.2 Legislators in the United States likewise have raised concerns, including proposals at the state and federal levels to regulate loot boxes.3 In addition, the video game industry has engaged in self-regulation, for example through the Entertainment Software Rating Board (“ESRB”) rating system, in-game purchase disclosures, parental control features, and consumer education initiatives.4 A mission of the FTC is to prevent deceptive or unfair acts or practices in or affecting commerce, which it achieves, for example, through civil law enforcement actions pursuant to Section 5 of the FTC Act, 15 U.S.C. § 45, industry reports and workshops, and consumer and business education. The purpose of this workshop was to provide a public forum to discuss consumer, industry, and academic viewpoints on loot boxes and related microtransactions. In this staff perspective, we highlight several issues raised at the day-long workshop and in comments submitted to the public docket,5 including the role of microtransactions and loot boxes in the video game marketplace, public concerns about these monetization systems, emerging academic research on loot boxes, and ongoing industry self-regulatory initiatives.

    1 Predatory monetisation? A categorisation of unfair, misleading, and aggressive monetisation techniques in digital games from the perspective of players Elena Petrovskaya, University of York David Zendle, University of York Abstract Technological shifts within the video game industry have enabled many games to evolve into platforms for repeated expenditure, rather than a one-time purchase product. Monetising a game as a service is challenging, and there is concern that some monetisation strategies may constitute unfair or exploitative practices. We asked 1104 players of video games to describe a time when they had been exposed to transactions which were perceived to be misleading, aggressive or unfair. We found 35 separate techniques over 8 domains: game dynamics designed to drive spending, product not meeting expectations, monetisation of basic quality of life, predatory advertising, in-game currency, pay to win, general presence of microtransactions and other. Notably, several of these reported practices seem to not align with existing UK consumer protection regulations. We discuss this potential misalignment, as well as the implications of identifying what players believe to be problematic monetisation techniques. Keywords: predatory monetisation, consumer protection, microtransactions, video games, in-game purchasing. Introduction The norm for revenue streams in the games industry used to be of a one-time purchase model, in which upfront payment was the only time a transaction was needed to guarantee a full gameplay experience (Lizardi, 2012). As underpinning technology emerged to facilitate continuous payment, monetisation approaches have evolved that treat games as potential sources for consistent expenditure, rather than a product in and of themselves. Since then, business models in the games industry have moved through several models, including pay-per-play, shareware, and subscription (Alha, 2020; Paul, 2020).

Lehtonen Objectives The main objectives of this study were to understand the elements of game design that affect the purchases of non-functional in-game content. An additional objective was to focus on the Games-as-a-service business model and how its structure influenced game design. Summary Games-as-a-service games have become increasingly popular within the video game industry, with one example of this being the battle royale game Call of Duty: Warzone. Research has been completed on various aspects of the industry, but not much research has been conducted on the design of games that utilize the Games-as-a-service model. Interviews based on Hamari’s (2015) research model were held to examine purchase influences in players.

  • Esports Business Models
    eSports Business Models Rohan Bose Mercer Capital www.mercercapital.com BUSINESS VALUATION & FINANCIAL ADVISORY SERVICES eSports teams make money in a variety of ways. In this eSports industry overview article, we discuss various business models for eSports teams. How an eSports Team Makes Money An eSports team can make money in a variety of ways, including broadcast revenue, sponsorships, merchandise sales, and subscriptions. The sources of revenue are detailed in Figure 1. Figure 1 Sponsorships As shown in Figure 1, sponsorships and advertising account for the bulk of revenue for eSports. According to Patrik Sättermon (Fnatic’s Chief Gaming Officer), “[I]t is estimated that around 95% of the money generated by our eSports teams comes directly from sponsorship deals.” The novelty of eSports has attracted many well-known sponsors; however, teams have struggled to make sponsor- ships a sustainable source of revenue. The relatively short life of popular games proves to be an imped- iment to sustained sponsorship. A game might be highly popular currently but within a year fade from public interest. © 2018 Mercer Capital 1 www.mercercapital.com Figure 2 IT/Computer related sponsorships are the most common in the eSports industry as gaming equip- ment and accessories are prominently displayed during events. For example, HP and Intel agreed to sponsor Activision Blizzard’s Overwatch League. As part of the agreement, competitors will exclusively use HP’s OMEN gaming PCs and displays. From a valuation perspective, consistent recurring revenue is a benefit to the value of a company. Spon- sorships can provide long-term recurring revenue to an eSports teams.

    STUDY Requested by the IMCO committee Loot boxes in online games and their effect on consumers, in particular young consumers Policy Department for Economic, Scientific and Quality of Life Policies Directorate-General for Internal Policies Authors: Annette CERULLI-HARMS et al. EN PE 652.727 - July 2020 Loot boxes in online games and their effect on consumers, in particular young consumers Abstract This paper defines loot boxes and describes their behavioural effects, including problematic behaviour. It examines the regulatory framework at EU and national level within which loot boxes operate, provides an overview of public and industry practices, and derives recommendations. Framing the debate around loot boxes, away from gambling and towards consumer protection, would provide the EU with an array of tools to address problematic practices and minimise potential harm, especially for minors.
