The recent success of video games that focus on creating content, rules and new solutions instead of just playing-through them reveal that the current research on game design and theory needs to be adapted. The mechanics behind these games are yet unknown territory. In our thesis we identify and analyse game features, mechanics and dynamics that transform the process of creating the content and rules of a game into a series of player's challenges. We provide an overview and insight how game design elements can be used as gameplay by comparing traditional game literature, discussing the influence and impact of social interaction features, and reviewing game design as gameplay games while developing an explorative game prototype. Finally we propose some first theorems and rules about games and mechanics that focus on creating rather than consuming.
