N64 like a lot of the Nintendo consoles had none of the games on the competitors, but often vica versa as well.

Smash Brothers of course started there

Custom Robo started there (only in Japan though)

You got all the rare games that were only on it. Mario Kart and Diddy Kong racing were there.

Mystical Ninjas Starring Goemon and Goemon's Great Adventure were the last 2 Ganbare Goemon games released in the west (and they're two of the most fun as well)

WWF No Mercy is one of the best wrestling games for actually playing the game and not watching sims.

It had everything except the big name titles that basically won the era, unfortunately.
