I've got all 3 of the main consoles, and my order goes like this:
Xbox > Gamecube > PS2.
I'll get games like Madden and SvR for PS2, as well as the Final Fantasy games, but if there's a game that's ported to all three systems (like Shadow the Hedgehog. November 17th, bitches.
), I'll ALWAYS get it on Xbox or Gamecube (Xbox mostly).
When I was watching Raw the other night, I kept seeing these commercials for the PS2 version of RE4. I've owned it on Gamecube since day one, and I LOVE it. So I'll have to buy it on PS2 just for the extras, the fact not withstanding that it doesn't look as great in contrast to the Gamecube version. I try to stay away from fanboy-ism, but it always kind of sneaks in there a bit. Why get a multi-platform game on a console that has worse loading times and slightly worse graphics?
But at heart, I have to claim that I'm a Sony fanboy, despite the fact that their console is the weakest of the three (technology wise, anyway). All my money is going on the PS3 when it comes out. Truth.
