I do still see it a bit insulting. Miyamoto has stuck to the same zelda formula for so long (yes wind waker looks different and has a different story but the gameplay is the same, and every portable zelda plays pretty similarly) He's done the same thing with Metroid Prime and Super Smash Bros. (that's not to say that Brawl won't be a crowning achievement). And the Mario Party series ! my god. And while I'm not saying he's very involved in all these I still say while the guy produces his own innovative games, he definitely has done some rehash. In fact, I'm gonna say I just think that okay bungie made a Halo 2 like halo 1... it doesn't matter, its only the second game. To insult a studio whos only made two big games is kinda harsh. Sure they gave way to demand. But, the also made a fairly good game. There's no reason they won't innovate more in future sometimes a studio just needs to get down its "barrings".
Myamoto aint directing Brawl. All the super-smash titles ever made are the works of other/younger employees. He (Shigeru) has admitted to liking Super Smash on the n64 despite "not being one of our products".
