1) Start from the beginning. Go download DOSBox so you can emulate all the really old games that are impossible to find or purchase anywhere.
2) Get StarCraft. You could play it for 12 years like they did in Korea. It's really cheap and amazing.
3) Get a Steam account and see what they have for free or on sale. Right now you can get GTA 1, 2, 3, Vice City, San Andreas, 4, The Lost and the Damned, The Ballad of Gay Tony, and Manhunt, Bully, and some other Rock Star stuff, all in a super Rock Star package for $43. They also have some cool free and/or really cheap indie games.
4) Get The Orange Box. Half-Life 2, Episode 1, Episode 2, Portal, Team Fortress 2. IT'S THE BEXT!
