When I had a PS2 I was a 9/10 Sony fanboy
When I had a Gamecube I was a 10/10 Nintendo fanboy
When I had a Xbox I was a 4/10 MS fanboy
When I had a Wii I was a 9/10 Nintendo fanboy
When I had a PS3 I was a 9/10 Sony fanboy
When I had a X360 I was a 7/10 MS fanboy
Wait, what was my point again... Oh yeah - being a fanboy is a fickle thing. It's not real. You 'die hard' fanboys will just as easily love the other consoles (except maybe Rol).
Also, you can be a fanboy of more than 1 console.
Right now I'm playing zero Nintendo games, but the Gamecube was just the greatest thing ever to me.
So (OT) yeah, I have done what the OP asks. Specifically, I did it when I bought the Xbox at the end of its life cycle. I played Halo,Halo2,Forza,Fable etc. etc. just to respect the console somewhat. And I have to say that Chronicles of Riddick looked WAAAAY too good for a last gen game
