I think that perfect dark is the best lookng, while OOT is the worst.

OOT is worst? Are you trying to stir the pot here, or are you being serious?

Conker's Bad Fur Day is the best looking, the worst is Cruis'n USA.

I'd vote for Conker being the best looking game. Don't have a worst looking game.

Star Wars: Rogue Squadron/Battle For Naboo.

Factor 5 are out of this world when it comes to pushing systems... both the N64 and the Gamecube.

Are we thinking of the same OoT, lol :P

Anyway best looking is Conker's, I dunno which looks worst but its probably some game no one knows about.

Superman 64.

I think Jet force gemini had amazing graphics and i'm biased here, coz i'm certain it had the worst gameplay too but i would have to say carmagheddon for the worst.

I thought Banjo Kazooie was better then Conker, but maybe I just liked the style more.

I would say Best looking game would go to Turok:Dinosaur Hunter
Honorable Mentions: Perfect Dark and Star Wars: Rouge Squadron

As far as worst, OOT isn't even close. Body Harvest would most likely be it, actually no Body Harvest 2nd. Superman, Hands down!
