Abe Stein, of the Singapore-MIT GAMBIT Game Lab, leads this session from MIT's CMS.608 Game Design course on how to brainstorm without letting social pressure or group dynamics kill good ideas. He draws on Alex Osborn's classic chapter on creative collaboration in groups, then has students practice generating ideas first alone and then together, comparing what each method produces. The session builds toward the class's first team project, a card game for two to four players, and ends with students forming teams and pitching early concepts. The lecture is less about game theory than about the mechanics of group creativity itself: how to keep quieter voices in the room, how to avoid premature judgment of ideas, and how a classroom of design students actually turns a vague assignment into a workable concept and a team.
