This would be my roster by series:
Mario, Luigi, Waluigi, Wario, Peach, Toad, Yoshi, Birdo, Bowswer, Geno
Zelda/Sheik, Link, Majora's Mask Link/Toon link(you can pick which one to use like Samus and Zamus) Ganon, Vaati, Nabooru.
DK, Diddy, Dixie, Tiny, K.rool
Fox, Falco, Krystal, Wolf, Leon, Panther
Pikachu, Jigglypuff, Mewtwo, Lucario, P.Trainer, Pulse & Minum
Ike, Lyn, Marth, Roy
Ness, Lucas, Claus, Paula
Kirby, DeDeDe, MetaKnight, Dynablade
C.Falcon, Black Shadow
Samus/Zamus, Ridley, Dark Samus
Olimar-ROB-Game & Watch-Ice Climbers-Pit-Isaac-Lip-
Sonic - Snake - Bomberman - Megaman
This adds up to 66 characters
13-girls
16- antagonists
Fix adventure modes repeditiveness. Make it so the characters fight each other more i liked this adventure mode when you fought in the battles like lucas vs wario, mario and pit vs yoshi and link. If they could pull this off then they could become creative with the storyline.
-I would have have it so 6 combatants could fight at a time, like multiman melees.
-No tripping
-Declone Ganondorf, toonlink, and lucas.
Star fox they can declone falco a bit more, but otherwise i like that they all play the same way, there fore i think they should just give them all a reflector, and a fire fox like recovery. And a Blaster, O and NO CLONED LANDMASTERS
-Make it so you can only air dodge once.
-No stickers, masterpieces.
-Give each character a home stage like melee did in all star mode
- bring most stages back, and any n64 ones bring them back but make there graphics spectacular.
-Better stage builder, trophies, items,
-Give alternate costumes(not alternate characters, thats a stupid idea)
Lastlly in the records, record the KO's computers get, why they stopped doing this in brawl is beyond me.
