The cornerstone of my childhood gaming was shooters. I grew up with platformers and the like, but as soon as the PS2 came out I was playing as many shooters as I could get my hands on; Timepslitters series, Goldeneye Rogue Agent were a couple of my starters,
I play MW2 on and off (mostly off), PDZ, Army of Two, GoW series, Halo 3, Halo ODST and a couple more.
My KDR usually involves me getting a few kills higher than deaths on average, more on an exceptionally good day.
