I bought the game on Steam recently and have been enjoying it. The game still looks great especially considering how old it is. I'm not crazy about the stealth segments but the atmosphere and game environments are impressive.
Recently went to a SLI config with a 2nd GTX 670 and got Metro Last Light for free in the process, so looking forward to its release next week!
