Don't forget the rumble pack. There wouldnt be a Sony Dualshock without that one. Although the dualshock is a bit better imo.
Back in the 16 bit era, I always found the Sonic games much more entertaining than SuperMario, so I had a Sega instead of a SNES. With the next generation, I used to play Tomb Raider and racing games, and Nintendo didnt have much to offer in that area. When the dreamcast, ps2 etc. came out, I was actually hugely dissapointed with the graphics, because there had been rumors that it was life-like. All of the consoles had serious aliasing issues, and a computer fitted with a good geforce or ati (even a geforce2) could do the job better.
I have a couple of friends who are huge Nintendo fans, so I can still get to play Zelda, Mario Kart, Mario Party and other good Nintendo games
