I still have mine too.
List of games I own, with how I rate them (I generally only kept the games I liked so they will all be pretty high) -
Hexen: B+
Pros: great if you like shooters, long interesting levels, cool weapons
Cons: Lame save system, barely a plot
Perfect Dark: A
Pros: Awesome shooter, great plot, Joanna Dark is a likable character (Before what they did to her in the 360 version), fun mechanics, great weapons, interesting plot
Cons: Not very groundbreaking, basically a rehash of Goldeneye with weapons I dug more.
BattleTanx - Global Assault: C
Pros: Fun battles, cool weapons
Cons: Repetitive, lame plot, nonsensical AI
Armorines - Project S.W.A.R.M.: B-
Pros: Interesting spin on conventional gameplay, fun enemies
Cons: Can be frustrating, terrible quest tracker
Zelda - Ocarina of Time: A
Pros: Fun gameplay, interesting story, long epic quest with lots to explore, great characters
Cons: Some of the dungeons can get tedious
Excitebike 64: B
Pros: Entertaining gameplay, great race and stunt mechanics, awesome tracks
Cons: Limited selection of players, tracks, etc.
Turok 2 - Seeds of Evil: A
Pros: Long complex levels, satisfying weapons, awesome plot.
Cons: Awful save system, I'm horribly bias to this game, so everything I love about it will piss others off.
Starfox 64: A
Pros: Great space shooter with fun rails mechanics, variety in the gameplay types throughout the games, lots of unlockables add replayability
Cons: Game itself can still be short, some of the characters can be annoying
Castlevania - Legacy of Darkness: B-
Pros: Challenging without being unfair, nice moody atmospheric game, lots of great interesting battles
Cons: Targeting system is not precise, not the best entry to the Castlevania series, not very many choices weaponwise per character
Killer Instinct Gold: C+
Pros: good selection of characters
Cons: Clunky fight engine, frustrating boss battle
Clayfighter 63 1/3: D (Not sure why I keep this game around)
Pros: Funny game doesn't take itself too seriously, interesting characters
Cons: Terrible fighting game engine
007 Goldeneye: A
Pros: Fun shooting game, variety of missions, extremely well made weapons and gadgets, tons of things to unlock, was pretty groundbreaking if you had never laid hands on a computer game
Cons: I can't stand James Bond. Some of the unlocks were extremely unfair to get.
Forsaken 64: B
Pros: Interesting physics defying gameplay, good selection of weapons
Cons: complicated level layout can be confusing
Doom 64: C-
Pros: Interesting level layout, New weapon or two never seen before
Cons: Worst entry into the Doom series, awkward graphics even for a N64 game, needlessly hard due to controls
Super Smash Brothers: A+
Pros: Probably one of the most fun games ever created, solid fight system, groundbreaking in many aspects, fun stages
Cons: Slim character selection
Winback: B-
Pros: Intriguing plot with a nice espionage Metal Gearish feel to it, multiple endings, underrated game with a solid cover and shoot mechanic
Cons: Clunky gameplay, can get very challenging especially if aiming for certain endings
Paper Mario: A
Pros: Good entry as usual, solid colorful light hearted game, nice spin on sidescrolling and RPG formula
Cons: Too linear, not a true sequel to Mario RPG
Aidyn Chronicles - The First Mage: B-
Pros: Solid RPG gameplay, decent length, nice equipment setup
Cons: Hard on the eyes even for an N64 game, too challenging from the get go
Ogre Battle 64 - Person of Lordly Caliber: A+
Pros: (Probably my favorite N64 game) multiple endings, tons of classes, fun battles, huge lengthy quest, interesting involved plot, open-ended in many aspects, lots of replayability
Cons: Battles can take a while to resolve, certain army setups can be at a severe disadvantage later on in the game.
Flying Dragon: A+
Pros: Awesome overlooked fighting game, great fight mechanics nice example of a fighting engine, two games in one, lengthy story mode, nice mix of RPG and fighting game, likable characters, highly customizable
Cons: Unbalanced, some characters walk all over others, some unlocks not worth it, some options are useless.
Mario Kart 64: A
Pros: It's Mario Kart you already know it's fun, great selection of modes, tracks, weapons, and characters
Cons: Rubber band racing style means you never really pull out in front, race outcomes can be based on luck instead of skill
Zelda - Majora's Mask: A
Pros: Fun lengthy quest, lots of places to see and explore, cool abilities
Cons: Dungeons can get needlessly tedious
Jet Force Gemini: A+
Pros: (Awesome overlooked third person shooter), amazingly awesome shooting mechanics, unbelievably advanced enemy artificial intelligence, fun and challenging never unfair, great selection of weapons, satisfying gun play, huge world, good plot, lots of comedy, many things to search out
Cons: Targeting system takes a bit of getting used to, certain areas not really worth exploring more than once, multiplayer was a little lackluster, especially coop
WWF No Mery: C+
Pros: Good character creator, large amount to unlock, fun.
Cons: Repetitive and simple
I've owned many other games, feel free to ask.
