Because some design choices shouldn't be defended.

And I have a hard time believing someone didn't have any issues with it. It's a pretty universal complaint this game has gotten. It was likely implented because of the 4-player multiplayer. I hope that never returns if it means we're stuck with that camera perspective. 

Understandably so. It's the least memorable out of them all. Still good but not really close to the others.

Out of the rest of the Mario games? It does seem on the higher end in that case.

Despite all its flaws, I really enjoyed Sunshine. Not my favorite but I still had fun with it. I must now prepare for the angry mob that will soon gather from my statement.

Don`t worry, you`re safe. You got comrades who think the same here ; )

Says who? You? 

You're mistaking me just stating my experiences for me hardcore defending, when that's not the case. I'm not saying "You didn't have any issues with the camera because I didn't" In fact, you're the one that's doing that to me. So please respectfully put this down, because literally this conversation isn't going to go anywhere.

Well this is how I see it:

Saying a 3D platformer needs an isometric camera perspective is like saying a game needs 24fps for a cinematic experience.

If you ask me 60fps is objectively better, just like a non-isometric perspective in a platformer is better than an isometric perspective. But most of my problems stem from the controls anyway.

There were some missions in that game that I absolutely despised, but other than that, it was a solid game.

Sunshine has the best controls. :p

Since the 3D Mario ranking is a thing, I say:

Galaxy > Galaxy 2 > 64 > 3D World > Sunshine
