Que? I'm going to have to look into this as I freaking love FO.
Vegas is the 'sequel' to vanilla Fallout 3, so if you liked Vegas you'll like the original too more than likely. Its $19.99 for game of the year edition, with all 5 DLC's for it. Also millions of mods for it, weapons and texture packs etc.
Believe i just encountered my first cheapshot tactic in Tribes: Ascend. On quicksand, the Eagle team just got the flag, and took it up to the roof of the central building where 2-3 technicians had set up shop with upgraded turrets. Try and get up there to take even one of the turrets out, you get fvcked up by the other two and the players...Instawin.
