Here we have identified more complex games, resources, and discussions. These games are a little more challenging to play, or may deal with more controversial topics. As one example of a complex game that has had big impact, Foldit is an online puzzle video game about protein folding. The game is part of an experimental research project, and is developed by the University of Washington¹s Center for Game Science in collaboration with the UW Department of Biochemistry. The objective of the game is to fold the structure of selected proteins to the best of the player¹s ability, using various tools provided within the game.
