my top 5 , 1 being my favourite:
1. James Bond: Goldeneye- Set the standard for all multiplayer first person shooters. Look at halo-halo3..
2. Perfect Dark- Same as bond, just better weapons, different levels. Story mode isnt as great tho.
3. Mario Golf- Just a good all round game.
4. Zelda- Amazing graphics for N64, Great story, just plain fun to play.
5. Mario Kart- What is better than racing little go karts around blowing up your friends?
