Maybe the N64 had a bit stronger first party output(I don't think so, but I guess many people do), but add in third party and the GC buries it. Nintendo games are always different though. Mario 64 is different from Sunshine which is different from Galaxy etc. Same with Zelda.
Third party was better on GC, but Rare left, and their output on N64 beat all the third parties on GC put together in my book.
Bet with Liquidlaser: I say PS5 and Xbox Series will sell more than 56 million combined by the end of 2023.
