Considering my only game on the gamecube ended up being Smash Bros Melee...and my N64 library was extensive (Not to mention I STILL play N64 games to this day) I think my choice is pretty obvious.
I'ma say N64. To me the best games came out for it. OoT, Super Mario64, Majora's Mask, Mario Kart, Pokemon Stadium 1 & 2 (Yea i kno...flame target) along with many others I cant think of atm.
not to be rude but that isn't a good question It's hard to answer because Gamecube has wind waker however N64 has Ocarina of time I can't say which one i prefer When you ask those questions make it better like n64 vs Playstation 2
