This is fascinating, if maybe a little depressingly predictable: a game called Bioshock that seems to incorporate Ayn Rand's philosophy in its background story. I'm guessing that it's hardly correct, although I'll reserve judgement given this review's use of such libels as the alleged "dog-eat-dog" aspect of Objectivism. I'm hoping that the game publisher knows Objectivism a little better than the reviewer, although I'm not that hopeful.
I'll likely buy and play the game, just to see what it's all about. Read the linked story if you have any interest in Ayn Rand and Objectivism.
