dude...it's well publicised that Miyamoto and his clique which includes Iwata absolutely detested Rare cos they were like tech wizards and every one loved them. Miyamoto was livid when he was told that Yoshis Island was shit compared to DKC...understandably cos YI is fucking awesome and DKC is dogshit.
Miyamoto never forgot and when he saw Dino Planet he decided to Cena the game and Rare as well because he knew he was over the hill and Mario Sunshine was going to be shit (which it was) and he couldnt afford to be shown up by Rare so he insisted they turn it into Starfox adventures. The rest history and Rare now make shovelware....ironically just like Miyamoto!
Comparing rare at its current stage and nintendo is just insulting
