The true sequel to Fallout 2 no matter what any idiot says. It's got deceptively deep storytelling that ends up spanning something like 200 years of lore, and some of the deepest characters in a modern RPG. This is the game that Fallout 3 should have been, and is an object lesson in RPG design in general.
Do you like TF2? Well have I got a game for you! It's TF2 but with um less stuff, and it's not as fun!
Sweet.
Dude. This game is so freakin huge and epic it's ridiculous. It's like the dope ass, hugest, deepest sequel to Asteroids that no one even knew they wanted. Buy this game for real dude.
