The Legend of Zelda:Ocarina of Time, I loved the story and at the time I thought the graphics looked so realistic, lol.

Pokemon Snap! I loved that game. Controls were easy, good game.
Another one would be Perfect Dark, which is pretty much the same thing as 007 except you're female. I play this game on my PC a lot.

   My absolute favorite Nintendo 64 game has to be Conker's Bad Fur Day.
   
   It was the first game ever to really be so dark and offensive in it's humor and it didn't become very popular and get too many sales because of it. Now that these types of games are more common, Conker's Bad Fur Day is becoming more and more popular. I actually found Conker's BFD on Vizzed's Retro Game Room and had a blast playing it! It is one of the funniest games I have ever played, with the cog bj scene, the bee and sunflower sex scene, and the stoner imps to name a few. Conker's Bad Fur Day is also great for it's movie references. There are a ton of references including some from Jaws, A Clockwork Orange, Terminator, and Saving Private Ryan. There is an entire area of the game based on The Matrix and Alien where you dodge bullets in slow motion while wearing and black suit and glasses and then you go fight a Xenomorph named Heinrich in a mech suit.


I also used to spend lots of time on this game speed running Conker until I realized that emulators loading screens were so much slower than Nintendo 64's so I knew I would never get a good time unless I got it for the N64, but guess what? It costs over 100$.  ;(

My favourite has to be Super Mario 64. It was the first game that I played on the Nintendo 64 and (as far as I can remember) not only the first game that I completed on the Nintendo 64, but perhaps the first game I've completed ever. I still remember the first time I completed it, with family watching me play the final Bowser fight. I was so happy when I completed it, I was crying, though I tried to hide behind a chair so that my family didn't see my cry. Ah, memories.
