I think I maybe missed some good games on the N64, but barely anything in the N64 library had much story or character depth, so it really didn't have anything to hold my interest. It had a bunch of fun and easy time wasting games that would include Mario and Starfox, but I don't think the system got off the ground the way it should have

The Playstation may have had a larger library, but that's mostly irrelevant except for the fact that it increased the odds of finding gold. And there was gold on there for me. With the end of the good Final Fantasy games FFVII was a nice experience, and the beginning of cinematic blockbusters with MGS. Also one of the best collections of obscure and beloved RPGs that actually made it to the west (unlike the SNES which had a comparable RPG library, but most of the best of the obscure was left in Japan). Grandia, Lunar, Wild ARMs, Brave Fencer Musashi, Alundra, and my beloved Xenogears. Its probably the system I've had the most fond memories with. Even though I went into that generation hating Sony for sticking their nose where it didn't belong and ruining the rivalry between Sega and Nintendo, I would have to choose Sony as my favorite of that generation now that rose colored nostalgia glasses are off

Edit: For the record, the Saturn was no slouch that generation. It may not have been able to compete with the Playstation's library, but I feel that it easily trumped the N64's library. Shining Force 3, Shining Wisdom, Shining the Holy Ark, Panzer Dragoon Saga, Astal, the best Street Fighter games with the best control for those games, Magic Knight Ray Earth, Dragon Force, Virtua Fighter, Daytona USA and Championship, Virtua Cop, Burning Rangers, Mystaria/Blazing Heroes, Blazing Dragons, ah the memories..
