why are some people mad that super mario galaxy 2 got a 10 in some reviews?

Galaxy 2's improvements and additions have a deeper impact on the core gameplay mechanics than GoW3's, which were largely presentational.

gameplay changes to GOW3 were as deep as SMG2

God of War 3 had s ignificant changes, particularly in innovations in magic and item management, but they did not change the gameplay as deeply as the changes in Super Mario Galaxy 2 have and I don't understand how you can argue otherwise.
