.Top 5 for me (I never owned an N64 but my mate did)
Goldeneye - spent weeks playing this it was incredible
Mario 64 - I was blown away playing this for the first time although I remember buying Tomb Raider 2 for my PS1 and thinking it looked better
Mario Kart 64 - Again like most enjoyed the endless multiplayer on this
Blast Corps - Tremendous; original game - actually forgot Rare did this until it popped up in the recent Rare Replay compilation
Body Harvest - DMA Design (now of GTA / Rockstar North fame) - great game fighting aliens but you could swap vehicles
.
Goldeneye my all time favourite,
Mario 64
Mario kart
Turok
Have you played any of those games recently?
Its good and fun! Brings back so many memories.
Can't believe there hasn't been love for snowboard kids yet!
Apart from the usuals I'll add f-zero x and smash Bros. I'm currently doing an OoT play through where my daughter watches.
Goldeneye
Star fox
Mario 64
Don't forget the Rumble pack.
But actually Lylat wars is probably better on the 3DS along with Zelda too!
