The Sim Game Gallery: 42 playable challenge games

Every game runs the same six-beat loop: a concept card with an example person, you manipulate the example yourself, Check answers your work, a consequence plays forward, Why? explains after right and wrong, then flat points. Filler photo and video blocks mark where real assets drop in. Content is placeholder pending expert review, nothing is wired to the engine.

Your inputs never move themselvesCheck always answers, never blocksNo penalties, ever Training wheels fadeA different person in every gameEvery health claim carries its study
