Telecommunications, Media, and Technology Development drivers: Third-party engines and mobile gaming By: Jayson Chi /// Terry Sun February 2015 Copyright © McKinsey & Company, Inc. Telecommunications, Media, and Technology Development drivers: Third-party engines and mobile gaming 2 A tiny but key component in the massive mobile gaming industry, game engines enable rapid innovation. Deciding on a third-party engine entails a range of factors. Worldwide, the total third-party game engine its two variants Cocos2d (for iOS) and Cocos2d-x market was worth about $130 million in 2013—an (supporting multiple platforms). Unlike in South amount dwarfed by the $13 billion collected by Korea and Japan, the Cocos variants lead the the mobile gaming industry that same year.
