Well stalker is what you'd call the 'latest greatest'. It kicks the shit out of old computers though so I doubt like 75% of pice has played it. I played the first mission this weekend but have been playing supreme commander instead. I just beat my first faction so maybe I'll try it some more. It's like oblivion if it was a FPS (guns).
It's getting good peer reviews (my peers are goons, the thread is gold 5/5 so I take it to mean it's an OK game)
