pretty revolutionary system, arguably more revolutionary than the Playstation 1 in that regard. first really highly used Analog controller for a home console (although obviously Sony followed suite quickly).
first debatably revolutionary open world 3D game (Ocarina of Time), first well realized open world platformer (Mario 64), arguably first hugely well received multiplayer and single player FPS for home consoles (007 Goldeneye, especially the multiplayer).
a load of great games for the time in an array of Pokemon games, Donkey Kong 64 (well mixed bag here but still overall well received), Banjo Kazooie, Banjo Tooie, Super Smash Bros (groundbreaking in itself), Perfect Dark, Conker's Bad Fur Day.
and I honestlyyyy kind of actually like the controller to this day. people seem to hate it who try to jump in and use it today, I suppose because its awkward to adjust to. But coming from someone who used it years at the time I actually kind of dig it. it doesn't feel that awkward in the hands, the only real issue is the directional bar on the left is awkward to get to.
everyone put on their N64's today and game a bit though! in honorrrr
