Dude, what do you want from us? Do you seek validation? Do you want attention? Do you want to spread nonsense? Whenever people tell you where you're wrong you just ignore it and repeat your same old stuff. Is there anything else you can do with your free time?
Clearly not capable of rational discourse.
So, instead, what's your favorite part of Mario Galaxy?
Personally I like the airship levels the best. Mario 3 was my childhood favorite, so it was a nice bit of nostalgia.
I also love the ice levels. Is there any real reason that walking on water as ice Mario should be more fun than just walking on dry land? Nope. Is it though? Yes.
And the music. Just all of it.
Do you mean me in particular? Perhaps you mean him, I'm not sure. As an attempt to distress him from all the bashing.
Well anyway, if you ask me, I enjoyed exploring all the little planets and discovering a ton of secrets everywhere. Also, like you said, the music is a banger from start to finish. I love that jingle when you grab a star. Also finding branching paths in the levels was satisfying to me. And despite being a game that is considered on the easy side I think there are quite a lot of stars that were hard to get and that took me several attempts, so in general I think the difficulty is very balanced and fair.
