In a few weeks, I'll be trading out my Wii for my N64 (as the system I have at college.) I plan on picking up a cart or two at a game store when I do so. I was looking at Perfect Dark among others. The ones I already have are: SSB, Mario64. Bomberman Hero, Banjo Tooie, Indiana Jones, DK64, Jet Force Gemini, Starfox 64, and possibly one other. O.o I also have Paper Mario, Sin and Punishment, and Kirby 64 on VC.
Please make some recommendations on what I (or others) should pick up. Thanks!

Perfect Dark is great. Zelda OoT and Majora's Mask are can't miss games either. Sort of surprised you don't have them. Mario Kart would be fun to play with friends too if you find it for cheap.

Goldeneye - still one of the greatest FPS games ever made.
Perfect Dark - see above.
Ocarina of Time - overrated but still great adventure.
Majora's Mask - darker, slightly strange Zelda game, but also well worth a look.
Diddy Kong Racing - better than Mario kart 64, a blast.
Mario Kart 64 - the worst Mario Kart game, but still fun.

Shadow Man is one hell of a game. Probably one of the best action adventures on the N64.

Thanks for the recommendations, especially Shadow Man as its one I saw for cheap and considered but didnt yet pick up because I didnt know much about it. I'll likely be fulfilling this transition sometime in November, so i'll update then with what I decided to go with.

Blast Corps is pretty good for when you feel like wrecking stuff, and if you can find either Body Harvest or Space Station Silicon Valley then grab those, especially SSSV.

Castlevania: Legacy of Darkness
Turok 2: Seeds of Evil
Robotron 64
Edit: almost forgot, Rush 2049

bomberman 64 was a pretty good platformer, and if i only played it a little at a friend's house, but i remember glover being pretty entertaining too. in addition to the ones stated above me, that is.

Blast Corps

Beetle Adventure Racing, DKR, and MK64. All three great 64 games.

wait a minute... HOW DID NO ONE MENTION DONKEY KONG 64?!?!? that is one of my all time favorite donkey kong games, and i'm a pretty big donkey kong fan. if you have any love for 3D platformers, and own a 64, you owe it to yourself to get it.

He already owns it.

Anyway, I definitely recommend Ocarina of Time and Majora's Mask, and Mischief Makers, if you ever locate a copy. Tetrisphere and Snowboard Kids 2 are also worth a look.

oops... so he does.... guess i missed that one. forgive my fanboyishness...

Super Smash Bros. is a good time, and Mario Kart 64 is very fun as well.

I wound up going to a thrift store this week and randomly found Goldeneye 007 for just $5.50!! I'm so excited to be able to play it again. Just need to wait until I go home for a weekend so I can bring my N64 up.
