The Stanley Parable casts you as a nondescript soul in a nondescript office building. From this mundane beginning emerges a skewed story of a man making choices, both small and serious, and a player expressing their importance in a video game. It's clearly a thoughtfully considered, deliberately tuned and - what's that? "We didn't actually think about this when we were designing the game"? So said William Pugh, one of the designers behind The Stanley Parable, the first-person adventure game that initially took form as a Half-Life 2 mod. Davey Wreden, creator of the original version in 2011, shared the stage with Pugh in a candid analysis of their game during the Game Developers Conference in San Francisco.
