I completely disagree with that philosophy. Maybe it's because I'm not a tourneyman, but I believe that the game was designed to be played with groups, and 1v1, and one-player modes were an afterthought. It's a party game first, and a serious fighter second.
How can anyone take an 8-inch-tall alien throwing what he believes to be carrots at a pink marshmallow that has eaten and stolen the powers and appearance of a giant green spiked Turtle seriously?
Alright, we haven't had a good old fashioned roster discussion in a while, so I'll just post what I believe to be a likely(Or at least possible) SSB4 roster, with a few of my preferences mixed in, and you can make what you wish of it.
All Brawl characters except Lucario return.
Newcomers are:
Toad
&Dixie(Gets added onto Diddy, as both a Tag-Team AND a Switch-Out(That is, ICs+Zelda))
Paper Mario
Tingle
Ridley
Medusa
Little Mac
Starfy
Samurai Goroh
Caeda(FE, placeholder for new FE lord; Although I do think if there is no new FE lord, she's most likely)
Zoroark
Meowth(Unless R/S remakes are happening around the same time; in that case, Deoxys, or another 3rd gen Pokemon)
Mega Man
Laughing dog(Duck Hunt, yes I'm kinda bringing this up, but we don't need a repeat of what happened last time)
Muddy Mole
Isaac
Villager
That's a total of 50 character spots, for a 5x10 grid, as well as 6 characters that don't appear on the CSS.
Perhaps you could download the ability to play as seperate Sheik, ZSS, Dixie, Squirtle, Ivysaur, and Charizard.
Although I would like downloadable veterans(Pichu, Lucario, Mewtwo, Doc, Roy and Young link), they're kinda unlikely.
