You have a similar story to mine. I was a Nintendo fanboy going back to the NES i got for my 8th Bday. Than the SNES and than the N64 which was the bread and Butter for me. Rare and Nintendo to me were the principle of gaming.

I also own a PS1 which i loved FF7 and Crash Series and Driver however i started slowly getting into PC gaming and consoles to me stopped being relevant. I did not buy a Gamecube, Dreamcast, PS2 and Xbox. It was until Halo 3 that sparked my interests. I am a huge fan of Sci-Fi and shooters, Dense Stories and great music and Halo offered everything.
I went back to play Halo 1 and 2 again thanks to the 360 BC and since than i called my Xboxes the Halo Box.
