Before I get into any discussion I must first say that the game is wonderful and you should play it. If you have already played it, don’t plan on playing it, or just don’t care about spoilers, then you should feel free to read on. Otherwise you should go and play The Stanley Parable and then come back. Go ahead and read Jim Sterling’s review as a way to motivate yourself.
If you’re still unmotivated to go and play before I go into my analysis, then consider this: How much choice do you really have when you play a game? Do your actions truly affect whatever narrative you are participating in? Does deviating from the defined path truly do anything? The Stanley Parable experiments with these questions in a fantastically intimate way.
