I turned 21 this past Monday (20th Oct) and with that came birthday money, and with that comes the birthday games spending spree!
I got 2 games for my birthday;
Bioshock, which is amazing
Brothers in Arms : Hells Highway, which has a great single player, but a pretty average online multiplayer
And, with my money I have bought/pre-ordered;
FarCry2
Call of Duty : World at War
Tomb Raider Underworld (Special Edition)
LittleBigPlanet
Guitar Hero : World Tour (Guitar bundle)
Fallout 3
Not a bad birthday, not a bad birthday at all
