Might as well ask why Doom doesn't let you look around with the mouse.
No it isn't. Don't be ridiculous. People don't say WOW DOOM IS NO INNOVATIVE, YOU CAN'T LOOK AROUND WITH THE MOUSE. No, they don't. But people DO say MARIO 64 IS BEST GAME EVER, IT IS ABSOLUTELY PERFECT when the camera makes playing the game a total chore.
Does the wii version fix the camera any?
Also, I find the stupid ass "revisit the same stage 99 times" game "design" even more offensive now than I did then.
At this point I'll be surprised if I even remotely like Galaxy, because it's obvious 3d Mario is the complete opposite of what I consider a good platformer.
