I know this is way off topic, and I have no idea how many of you are gamers. But one of the latest shooters out for the Xbox 360 and the PC has the coolest art deco 50s environment in the world. The basic premise is a utopia society gone very, very wrong - but like I said, it was the environment itself that caught my attention right off the bat. Take a look for yourself at these blogs that talk about Bioshock:

Destructoid’s Bioshock review (scroll down a bit to see some screenshots, the entire game is set with that art style, it’s badass)

Bioshock, Symbolism, and Mind Control (interesting read into the depth of the game, along with some videos that, once again, show off the retro environment)
