It doesn't make any sense to me to bring back a "character" that would easily be an alternate costume.
Dr. Mario is different in a sense, yes, but isn't his running speed/jumps/recovery/etc all the same as Mario? Maybe he was in to just shove in a character.
However, all the past Smash games do not have "clones" together unless they're with they're series.
Falcon and Ganondorf are next to each other, but Ganondorf is still next to his series.
Dr. Mario and Mario are touching, but they are still in their own series.
Same for Falco/Fox, Same for Pika/Pichu/Marth Roy.
They are next to each other but they are still within their series.
Same for Brawl:
Fox/Falco/Wolf
Mario/Luigi
Ganondorf is within his series
Toon Link is not next to Link but within his series
Ness/Lucas but within their own series
So for Smash 4:
Why are Dr. Mario/Dark Pit/Lucina not with their main series? Its pretty much always been characters stay with their series. It just makes sense. It's organized. That's Sakurai.
I don't think these are all of the characters.
Has anyone thought there are 53 characters? That would make the entire screen complete. It looks like to me everyone is not unlocked yet.
Even if that's the case, its INSANELY odd that all the clones would end up together.
Also, characters like Villager/Wii Fit trainer were HIGHLY promoted and shown off. They're on the box art. Why would they be so far down to the bottom two rows of the screen? It doesn't look right at all.
Also, the top would basically be all Mario & friends characters if Dr. Mario was replaced where Mr. Game&Watch is.
I can see Mr. Game & Watch together with PAC-MAN. But not next to Bowser Jr. That's so...random.
