Just thought I'd give you some info before you judge me as a microsoft fanboy.

C64 - Yes, that's where it all started... it wasn't mine, but my cousin's. I spent countless hours I can't remember in front of that thing, can't even remember what it looks like now...
NES - My first console. Started off with a little SMB, but soon got a taste for MM and TMNT. Also played some T&T, NWC, BM and in later years FF.
SNES - Again, another console I've spent a lot of time with, but wasn't actually my own. A few of my all time favorites are on this console, like SMW.
PS1 - My second console. The PS1 has so many classics, I don't know where to begin. This console is also where my favorite game was released, FFVII.
PS2 - My third console. The last time I counted, I owned 80+ games for this console, but I'm not sure what the total is. Favorite games include MGS3, GT4, T5, MKD, FFX and many more.
360 - My fourth and current console. Own a few games for it; Forza 2, Viva Pinata(bundled, and I'm kinda glad it was), Mass Effect, Skate, GTAIV, FIFA 08 and Oblivion. Got it in January.

Honorary mentions:
Genesis/Mega-Drive - A memory dimmer than the C64, I can't remember much more than Sonic. Good console, but I'd rather have my NES.
Gamecube - My brothers trusty old gamecube is still going strong, to the point that I've almost become indifferent to Mario as a game character.
PS3 - Haven't played a lot, I think it has the potential to be great, but Sony keeps dropping the ball. There's something odd about the controller too...
PC - Until a few years ago, I held my PC in higher regard than any platform, mostly because I really like to mess with games... but then windows deleted itself and I'm computerless...

So, that's it. I started out as a Nintendo fanboy, I turned to Sony for two generations and now I'm with Microsoft. Next generation depends on the consoles, which is why I wait for at least 6 months before I buy.
