The 64 was the first console with an analog stick and the first console with a vibrating controller. However being a cartridge based system, it had inferior sound quality. But becuase it was a cartridge based system it was very reliable (Good luck finding a broken one.) Also cartridges have less space on them then CDs, so Nintendo lost alot of 3rd party support. Cartridges are expensive and companies didn't want to pay tons to put a huge game across multiple cartridges.
The 64 had smoother graphics then any other console that generation, though the colour palette had heaps of crappy oranges and such.
The 64's controller was revolutionary, but crap. The analog stick could be worn out quickly (If you want your controller to last stay away from Mario Party.) Also the c buttons were hard to reach.
Some popular 64 games are: Super Smash Bros, Super Mario 64, Mario Kart 64, F-Zero X, Mario Party, Mario Tennis, Zelda: Ocarina of Time, Perfect Dark, GoldenEye 007, Conker's Bad Fur Day and Lylatwars.
Person 2: "Yeah, I first saw the title screen, ran over, pushed away all the little kids shoving Mario's mustache up his nose, man did my Playstation games look tired then. I'll never forget that."
Me-So why would you get all those game systems and spend tons of money on them when you could just play Nintendo 64 and have just as much, if not more, fun?
Kid-So I can brag to all my friends. All I want is to fit in. **cries**
