Not sure about the Project M sounds but I expect it not to be so different from Brawl and I just have to say that the SFX in Brawl is so amazing. Was watching my friend play Brawl and I was just listening to the sound effects, and the metal clanking of Metaknight's blades and Lucas's PK Fire in stuff. Not sure if it's just me but it sounds much better than the Sm4sh sound effects for some reason.I personally like how Pk Freeze looks in Project M. Just the sound and the little ice animation makes me happily wanna combo into oblivion.
