Honestly, I don't get how anyone can hate on the roster. They included so much and so many different characters. Yes, some of them are "almost" clones of other ones, but come on---there's easily someone for everyone. No Mewtwo, but you've got how many other Pokemon included? And I love that Kid Icarus is getting some slots, especially Palutena, who I can't to try out. They're bringing some fresh blood in from all sides as well as a lot of old favorites.
There's just so much to love about this upcoming game that I can't even fathom the hate and complaints.
Besides, we're in the generation of DLC. And that in itself is amazing. I'm almost positive they'll end up having Smash Bros. DLC upcoming.
