Everybody knows and agrees that the gaming "scene" has literally exploded. From a global market of USD 4.29 Billion in 2015 to an exponentially bigger market of USD 45.09 billion by 2025, is no coincidence! 

​

When you calculate all the time that gamers everywhere pour into one of their favorite games, the statistics are simply staggering. "World of Warcraft's legion of devotees, for example, have now spent more than 50 billion hours- about 6 million years- roaming their mythical, digital universe".

According to Jane McGonigal, the allure of games can be used for good. Games challenge us with what she calls "hard fun" (hard work that's satisfying). Games can improve our social connections, and they can provide a huge arena for collaboration.
