16-bit... I prefer the SNES. The console and controllers are incredibly reliable, you would really have to fuck one up for it to stop working. Also, all the classics... Super Mario All-Stars, Super Mario World, Super Mario World 2, DKC series, Zelda, Super Metroid... the list goes on and on.
Currently it's the only console I own. I've simply gotten bored of gaming, which is hard to believe since I grew up doing it. When my sister announced she wanted to take my PS3 to college, I didn't object, simply because I'd gotten tired of it. The only game I had enjoyed on it in years was Dark Souls(don't get me wrong though, while I didn't think it was a 10/10 game, I still had fun with it).
Originally I was a huge Nintendo fanboy... but I dunno... ever since the Wii... the Wii is what made me make the switch to the PS3. The PS3 was better, but still not amazing. Tried getting into PC gaming, but the only games I really enjoyed were the early Elder Scrolls games, L4D, and some indie games...
Maybe I'm still a Nintendo fanboy at heart. Maybe, all I have to do is look past the gimmicks, lack of difficulty, lack of third party support, lack of hardware power, and I'll see the Nintendo I saw in the N64 and SNES, and even a little bit in the Gamecube.
I always have liked 2D games better than 3D ones...
