Woo new thread. Gotta say, I'm totally satisfied with the roster to the point there's not much I'd want left. Shulk (my most wanted character that had a realistic chance of getting in), Robin/Lucina (I technically wanted a FE:A rep at all, but two is awesome), Greninja (my favorite Gen VI Pokemon and one of my favorite Pokemon in general), Little Mac, Palutena and Mega Man! Not to mention, Ike and Lucario return, both characters I really like that I was concerned that may be cut. I don't even mind Dark Pit or Dr. Mario that much, and I think Duck Hunt Dog could be really cool.
October 3rd can't come soon enough!
This, honestly Dr. Mario is the only "Blemish" if only because I'm still salty over Roy being taken out. (Though Lucina is an excellent addition)
