Basically I'm a massive XBox and a sideline PC man. And have been from the start.
Nintendo was a big player in my life till they started worrying more about the mainstream ,with the Wii, rather than the core gamer. Same reason for anyone else who's lost faith in them I expect.
PlayStation was also the big cahonas while i was growing up and  i was never up for following the crowd so i stayed away most of my early years. Until now when i am seriously considering buying a PS3. Metal Gear and Little Big Planet are big favorites of mine at the moment. Bet there is still something missing i think.
I currently only own a 360 as i have just sold my Wii.
Games i own are countless PC games that are scattered throughout my room and these 360 games; FIFA 09, Riddick, Halo 3 and Street Figher IV.
