I was a Nintendo fan first since the NES and Genesis 2nd (like there was any other competition lol)
And I even tried to be a N64 fan over PS1 but eventually I couldn't deny it anymore and loved what PS1 had to offer more than the N64. And from that moment on I became a Sony fan first and Nintendo second.
Random memory: I remember when Resident Evil 2 came out for N64, i was like "Ha! we're (Nintendo fans) getting all those PS1 games too!" ....well that was short lived lol. And I was excited that N64 was going to get RE0 but that cancelled and moved to the Gamecube. But boy N64 had the best wrestling games by THQ. Also N64 was the last system I enjoyed playing wrestling games, onwards just wasn't cutting it for me anymore.
