This has been said before, but I just want to restate. When the N64 was failing Goldeneye, Ocarina, and Banjo Kazooie came out within about a year.
Did people love these games? HELL YES.
Did the system get saved? no.
First 3D Zelda > Another Final Fantasy
Goldeneye > MGS4
Banjo-Kazooie > KillZone 2
