This is a brilliant offer. I can say without prejudice (lol) that Fallout 3 is one of 2008's biggest games. I couldn't stop playing it for weeks and clocked up over 200 hours of playing time in just the first two weeks and still hadn't scratched the surface (well almost). The deal coincides with Fridays PC release of official content that includes The Pitt (Pittisburg). It's been out for some time on XBox and Playstation. There will be more later this summer. Also there's a growing community of Fallout 3 modders and loads of mods to be found to expand on the already rich game. If you're strapped for cash, and can only afford one game in the next few months this should the one you choose. It was developed by Bethesda who also created Oblivion. In fact they have used the same games engine to build Fallout 3.
You'll require the Steam client, and an account (both of which are free) before you can purchase the game.
