Ddue, you just missed out on that ridiculous sale that ended recently. It was GTA4, Bioshock 1 and 2, Fallout and ME too, I think. You should have gotten on that and saved some big bucks. I'm on a Mac so I couldn't get all the games, but it was definitely a good deal.
I played F3 for a bit before and it was just weird. I have heard a lot of good things about Mass Effect and I have it for Windows, I just have to run Boot Camp on my Mac and finally try it. Otherwise, I think I gotta get the game somehow, either for 360 or PC. Might be cheaper used for the 360 at Gamestop.
