1p - Lucina chan
Done. Well, I'm going to bed now, it's getting really late. So, I'll add my vote and be done for today, don't expect OP updates for the next 8 hours or so.
My list will basically be how likely I am to main a character. I know that's not exactly the same as "looking forward to playing", but it's more relevant. I know I'm really looking forward to playing Inklings, but I also know I'll probably be done with them after a few rounds. So,
5p - Meta Knight (absolute main, he's here to stay.)
4p - Fox (might pick him back because he'll be available from the get go, and he seems different enough that I can't just auto-pilot, which was one of the biggest reasons I dropped him in the first place. Having to relearn the character is exciting.)
3p - Bowser (he's cool and I'm planning on keeping him around my pocket, but he does look a little worse in this game. Time will tell)
2p - Falco (looks better and god I hope he's better. I'd have picked him often in Smash 4 if he was actually competitive)
1p - Ridley (he's Ridley)
Honorable mentions: Wolf (never played Brawl, so as a Star Fox fan I can't wait to try him out, and who knows maybe I'll like him more than I expect to), Inklings (I'm sure they won't suit my style, but they're still so cool), Samus (always had fun playing as her but being unable to charge in mid-air irked me way too much, thankfully that's been fixed), Ganondorf (was always a blast, now he looks even cooler!), Marth (again, always a fun time, and he actually looks OP now)... I could go on, actually, but that's probably enough. Yep, too many damn characters.
