Ski Stunt Simulator may very well be my all-time favorite physics game. As with most physics games, the premise is simple: You control a 2D skier performing various tricks on the slopes. Where Ski Stunt Simulator stands apart from other physics is the fidelity of that control. This isn't a simple ragdoll game-far from it. In fact, Ski Stunt Simulator is the result of collaboration between a programmer at Relic Entertainment and a researcher at the University of British Columbia, and the robust simulation definitely demonstrates an academic level of engineering.
