I don't play a lot of games, but my friend Craig loaned me his BioShock discs for Mac couple of years ago and I enjoyed it. The super creepy dystopian universe is a critique of Ayn Rand's simplistic political and economic ideas based on the concept of "rational self-interest." Amazon has a sale on all three BioShock games in the series for the Xbox One and PS4 for $30. If you don't already have this game, this is a good time to get it.
