Just looking at my top 10 or so on each systems it's basically a Tie. PS1 wins on hardware front and on the sheer scale of it's library though.

388 N64 Games vs 2449 PS1 Games....

I love them both equally now, but If for some reason I was stuck with just one for a long period of time it'd be the PS1 I'd choose. I think I'd run out of things to do quicker with the N64.

I liked both consoles, but, PSX is my favourite console of all time. When it was out, there were always great games coming out for it. Plus, 3 of my top 10 favourite games of all time (including my favourite, Xenogears) are on that one console. Aside from SNES (which has 2), no other console has more than 1 of my favourite games. I would also say about half of my top 40 favourite games are on PSX.

The first thing I could call a drought on a Nintendo console happened in 1993 when the only really interesting things that came out were Mario Kart and Secret of Mana, I can't recall much of anything else, but that was NOTHING compared to Super Mario 64 until Ocarina of Time, and aside from the Wii era, Nintendo hasn't yet been able to shake the rampant droughts.

As much as I loved Ocarina of Time, Banjo Kazooie, Majora's Mask, GE007, Conker, and Mario Kart, it just doesn't compare to console gamings trongest lineup of RPGs in history: FF7, 8, and 9, Suikoden 1 and 2, Xenogears, Parasite Eve, Dragon Warrior 7, Wild Arms 1 and 2, Breath of Fire 3 and 4, FF Tactics, Vagrant Story, Chrono Cross, Legend of Dragoon, Grandia, Valkyrie Profile, Alundra, Brave Fencer Musashi, Legend of Legaia, Front Mission, Lunar SSS Complete, Lunar Eternal Blue, and it goes on. That's not even getting into our Resident Evils, Tomb Raiders, MGS, Street Fighters, and so on.

I'm as big of a Nintendo fan as they come, but I'm not going to blind myself to the times when Nintendo is clearly screwing up, and despite having some great outings, the N64/GameCube era was a very dark time to be a Nintendo fan, and PSX was much closer to what you'd expect from an SNES successor than N64 was.

When it comes to the golden age of console gaming for the sort of gamer I am, it began in 1994, midway through the SNES era with FF6, Illusion of Time, and DKC, and ended in the early years of the PS2 in 2002 with FFX and Vice City, but the majority of that golden age took place on the PSX, and that is where (in my opinion) console gaming reached its zenith.

N64 is my favorite Nintendo console, but the PS1 is my favorite Sony console. Some of my favorite games of all time are on the 64, like SSB (I dislike the sequels). However, PS1 had a much bigger library and absolute classics like Tekken 3, Gran Turismo 2, Medal of Honor.

So, PS1 gets it by simple sheer amount of absolute classics. It also helps that the N64, while more powerful, frequently would get a version of a 3rd party game with unwatchable cutscenes or crappy/missing soundtrack to fir the cartridge. Quake 2 is a good example, missing the absolutely AMAZING music of the PS1 version.

N64 changed gaming and moved 3D gaming forward. But PS1 had just way more games and thanks to third parties PS1 also had triple A games

One of the things that equalizes it a bit for me is that I'm generally not fond of RPGs, for that matter MGS/Tekken/Gran Turismo/pre-RE4 Resident Evil.

For me the highlights of the PS1 were stuff like Crash Bandicoot, Wipeout, and Spyro.

PS1 by far. There are so many games on the console that are must haves for me.

Final Fantasy VII, VIII IX
Resident Evil 1, 2, 3
Crash Bandicoot 1, 2, 3
Tekken 1, 2, 3
Silent Hill
Parasite Eve
Dino Crisis
Metal Gear Solid
Street Fighter Alpha 3
Xenogears
Castlevania: Symphony of the Night
Spider-Man
Legend of Dragoon

Compared to the N64
Super Mario 64
Super Smash Bros.
The Legend of Zelda Ocarina of Time, Majora's Mask

At the time, definitely the PS1. The music, the controller, the cgi, the quantity. Couldn't be beat.

Now? Probably the N64. It just had more multiplayer games and timeless classics. It's close, though. Those 2D games on PS1 are still great and there are a few games that still good despite the crude polygons (Intelligent Qube, Incredible Crisis, Parrapa).

Too close to call.

too late to stop this (necro)train.

PS1 had a larger and more diverse library, but N64s 4 player capability and classic nintendo offerings gives it the edge to me. SSB, MK64, WWEvsNWO, Star Fox 64, Goldeneye to this day are some of my most favorite multiplayer games. On the single player side, it had SM64, the Zelda pair, Yoshis Story, Banjo, Conker...

oh yeah and F-Zero X, my favorite F-Zero.

64 by miles. May not have as many games, but has some of the best games ever, and THE best game ever (OOT)

I've never played either. You know I really hate it when people say "I was born in the wrong generation! I wish I could have grown up in the 80's!" But honestly sometimes I wish I was like 37, so I could experience the SNES/Genesis, PS1/N64, and the 6th gen. Not necessarily to become crabby or hate on modern gaming or to play "De best gamus evar!!!" but just to have more perspective on gaming as a whole.

That being said, Xbox 360.
