In the context of console gaming, I'm not fanboy. No one console company has a monopoly on my gaming interests. No chance in hell am I going to be a one console person. I go where the games I want to play are.
And right now that means the Xbox 360 and the Nintendo Wii, I'm not giving up one console just because I'm playing another one. I'm just enjoying myself in all the great games I can play, and one day.. with my son.
That said... bias wise I'll always lean towards... Nintendo for giving me the best gaming experience since.... hmmmm... a long long long time ago.
