Didn't Rare have some wicked founding as well? I recall reading that Banjo-Kazooie (or was it Tooie?) was more expensive to make than SM64
As Rare failed to do anything great right away for Microsoft, they didn't give them a lot of founding, which causes their games to lose quality.
That could be part of the reason...
