Game design involves choices that both players and designers make. Players aim to choose rationally to maximize benefits, though human decision-making is imperfect. Designers can restrict choices through the game's structure to control the player experience and steer them towards intended outcomes, similar to how experiments control variables. Game design and restricting player choices are thus about controlling the player experience through their options.
