Abstract: People play video games. Many play seriously not just as a hobby. Yet educators either criticize players or resist including games in their curricula. Wouldn’t it be great to harness the enthusiasm that already exists for players into educational settings? This study actually asked game players to identify video game genres and explain what they learned from playing games. Twelve main genres were identified. These genres were: role-playing games, massively multiplayer online role-playing games, first person shooter, sports, puzzle, real time strategy, action, turn based, simulation, fighting, kinetic controlled, and casual. In addition, the study identified 19 learning constructs described in the paper.
