Banjo Kazooie.

It was my favourite game of all time until I played RE4, just an absolutely magical experience through and through, from its unforgettable worlds to its immense variety to its whacky Rareware charm.

The correct answer is Super Mario 64, but I need to give a shout out to Mario Party 2 and 3

Super Smash Bros.

Pokémon Snap is my favorite on the console.
Other games might be of higher general quality, but Pokémon Snap did something no other game did. Was disappointed when I first played the game, thought that I could walk freely and searching for Pokémon. But the game grow on me
I still want a free-roaming version instead of the on rails ones we have. If needed, make levels with time limit to keep it possible with scripted events and such.

Goldeneye 007 is what I played the most by far besides Mario Kart 64z

However, on the Wii virtual consoles and beyond it’s been Ogre Battle 64.

Mario kart 64. Seeing it/playing for the first time at a duty free store , airport, was the most amazing thing id seen.

For me it's Super Mario 64 and GoldenEye 007

Only ones I've played are Mario 64, Paper Mario, Zelda OoT & MM and Conker's Bad Fur Day.
I'll have to pick Ocarina of Time.
