Well, previews of Bioshock (a game that's to be released)looks pretty sweet, and provides many social commentary. It portrays the atmosphere really well. You get a sense that you're staring at a 40's scene rather than several gunned down soldiers in a destroyed city. There doesn't to be anything extremely over the top (other than the multiple ways to manipulate objects); Bioshock just "delievers".

'Nuff said, I can't put my any more brain on it. I've only read Bioshock's news for several days. Hopefully it will be an artsy game.
