So i broke out my N64 recently, after i got a replacement video cable i found my collection of games surprisingly lacking (probably due to my enormous PS1 games collection). 
 
So it's over a decade later, what games do you think best show the shine on the N64's golden days? What did you never stop playing?

Ocarina, Shadows of the Empire, Star Fox 64, Mario 64, Golden Eye and Perfect Dark.

Okay scratch that, i have all of that. Man the N64 was more barren than i thought >_>

" Okay scratch that, i have all of that. Man the N64 was more barren than i thought >_> "

Mario Kart, Blast Corps, Killer Instinct Gold, Jet Force Gemini, the Turok games, F-Zero, Body Harvest, Conker's Bad Fur Day, both Mystical Ninja's, Donkey Kong 64, Mario Golf/Tennis, Pokemon Stadium 1/2, Rogue Squadron and Glover?

Pretty much all the games already mentioned are the best to have in your collection. Although Paper Mario is also a great game.

I've been rebuilding my n64 collection. A lot of games just don't hold up very well...and, unless you got a few nostalgia-laden friends, multiplayer games just won't really be all that useful. I don't think I could really convince anyone I know to play n64 multiplayer games, so I only have fun singleplayer games I can still use. Anyway, here is the list of games that I know of:
 
Obvious/Popular:
Super Mario 64 (Still a fun platformer and very different from modern mario games in its open ended approach)
2 Zelda games (OoT was still great to play through again. Just beat it recently. I've never played MM, but will soon)
Star Fox 64 (Unless you hate rails, it's worth a try)
Goldeneye/ Perfect Dark (Some people say these games don't hold up well. I think they still have a distinct flavor to them. But even then...people loved it for its multiplayer...)
Super Smash Bros. (Self-explanatory. Holds up even if it's a bit slow compared to the other newer ones, but it's a multiplayer game.)
Mario Kart 64 (Again...same. Still controls well and looks fine (by n64 standards). )
All other well-known n64 platformers ( banjoes and donkey kongs, etc.)
All other racing games (fzero, beetle something or other, ridge racer, sf rush games, wave race)
Pilot wings 64
Paper Mario (played it recently alongside the GC one. loved it. Just as fun as the newer installments. The graphic style works great) 

Not so obvious:
Mischief Makers (A Treasure game. 2D for the most part I think. Graphics kind of look like Gunstar Heroes. It's weird.)
Goemon games (there were 2 of them. First one was a 3d platformer, second one was 2Dish. both are considered good...and weird too.)
Blast Corps (destroy stuff with vehicles. fast, fun, but can be really hard and frustrating later on)
Harvest Moon 64 (well, this is kind of obvious, but still niche I guess. Still one of the best in the series. one of my favorite games ever.)
Resident Evil 2 (a popular series, but if you've already got it on PS...well...)
Doom 64/Duke Nukem  (don't know about duke, but doom is completely different compared to PC version and not in a bad way.)
 
Games I got rid of because they did not age well:
Gauntlet Legends (An ugly mess. Not very fun either. )
Rampage (looks great....but completely repetitive and boring.)
Megaman 64 (Same game as Legends on PS. Feels really slow paced in its story and controls were weird. Some might like it if they can overlook those issues)
Turok (I think it was the first one. Really...I don't think these games were fun. Odd platforming. Very confusing worlds. Awesome guns. Best to stick with the more renowned FPSes).
Battle Tanx: Global Assault (Cool tanks and powerups. But...I don't know, it was just kind of frustrating.)
JetForce Gemini (Graphics are decent. Gameplay is okay. I remember a lot of annoying back tracking and collecting though.)

Besides the obvious ones (SSB, OOT, SM64 etc), Harvest Moon 64, Road Rash 64, Jet Force Gemini, WWF No Mercy

@Jadeskye: If you've played it reciently, maybe you can help me out. I decided I needed to play Majora's Mask- and instead of just buying it on a Wii or something, I bought a n64 cartridge (and the N64 RAM expansion pack) and booted up some old games- and christ- they look terrible! I mean, not just because they're aged, but because it's been years since I've played n64 games on an SDTV. Banjo Kazooie looks great when played on an emulator- but when playing on a PC it's so blurry I can't even see the pupils in his eyeballs- and when I play Zelda, everything more than a few feet out from the screen is so blocky it's unrecognizable- have I been spoiled by Wii ports- or could my old-ass N64 be acting up?

@TooWalrus: i think you're spoiled my friend. it was a very blocky time.
