For what i said about banjo-tooie, i have the game also (i do own all N64 rare games) but at the end of the N64 era they just made the games too elaborate. In the beginning you had banjo-kazooie and goldeneye and gemeni and those were just great games both by gameplay, graphics and simplicity. But like tooie, at the end you had cross links between worlds etc etc, i haven't finished the game. I don't say it did not deserved it scores, but it could have been better if they just kept it easy.
Rare was indeed slow on releasing games, they just had that many teams to make it up. I remember kameo being presented for N64,GC,Xbox and it finally hit XBox360.
I don't think Rare should do Donkey Kong, i think they should do Duke Nukem Forever :)
I do want to thanks Rare for re-releasing Conker bad fur day on the Xbox, it proved that Graphics don't matter and that Nintendo was willing to lose it 'childish' image: only the Xbox version was censored.
And yes we should thank them, but since the Stamper brothers drive to work in a ferrari i think they already got their little presents :)
