Research also showed that serious in serious games.

In serious games the "player"faces these two problems spaces simultaneously. This can be problematic because the player might focus mainly on one problem area and therefore lose 1.

Another problem can be the complexity of tasks and instruction. Games in this context are referred to as to be performed that degrades the appeal of serious games. serious games [1]. Serious games are grounded in active The player must learn the game mechanics, understand the learning and encourages learning activities by building on learning material of the serious game, and understand what engagement and challenges to achieve the intended learning the relation is between the learning material and the game objectives [2]. mechanics in order to figure out the gameplay. 1https://minecraft.net/en-us/ Most studies regarding serious games were to be found fo- cusing whether players understand the learning material [5], engagement and motivation [1]. However, no studies (as of this date) were found that investigate whether players were able to understand the gameplay of the serious game, which provides an essential contribution to its appeal. The appeal comes from play which is a fundamental part of the moral self-being, of the healthy and mature human life [6]. In this paper it is investigated whether the understanding of the gameplay is affected by the complexity of the game • have a conflict mechanics in serious games.

So, games can be described as having goals, rules, challenges, 2. RELATED WORK interaction and stimulation. These definitions essentially 2.1 (Serious) Games show that games can be seen as a problem-solving activity in form of some sort of conflict or puzzle (goal / challenge) Throughout time many researchers and philosophers have that is structured by rules. given their definition for what a game is.

These type of games are being used for training [15], education [16] and health [17]. Seri- One of the earliest philosopher to discuss games was Ludwig ous games are games that engage the user, and contribute Wittgenstein [1953]. He argued that elements such as play, to the achievement of a purpose other than pure entertain- rules, and competition fail to define what games are. The ment.

Therefore, commercial off-the- [9]. shelf (COTS) games, used for non-entertainment purposes, can be considered as serious games [18]. According to Roger Caillois [1957] a game is an activity with the following characteristics: fun, separate (as it is circum- Minecraft2 is such an example.

This has led to many worlds created by different players. This paved way to the application of Minecraft in the world Crawford [2003], in his definition, talks about conflict in of serious games. more detail.
