I love the hitman series and played the hitman: blood money demo and i am already addicted to the series. Then after I played splinter cell recently, I realize that I like those games too, plus with the current season of 24, i was inspired to buy Rainbow Six Vegas. Then of course, there's shivering Isles, the expansion for oblivion, which I own. I have vista, which is the one deciding factor in terms of compatibility. Also, i have 2 gigs of ram and a high video card so its more about the game rather than 'if i can run it at all'.
