Less clones.
Knuckles might be fun, he's already in a lot of Smash Flash type games.
Moar Fire Emblem.
Less Metaknight.... Or just make him the absolute worst character... xD
Get rid of toon link or regular link, although I agree they are both pretty distinct, there's no reason to have a clone as close as that when it would have been much more appealing to put in an entirely new character.
No Megaman. =/. I don't even know why, besides the fact that he's quite similar to Samus, but I really dislike Megaman.
Maybe Zero though, Zeros cool. Even though he might be a little to much like Marth....
Maybe take out Ganon? He's never been too unique, and IMO, Falcon is much more fun.
I'd mention more characters I'd want in, but I think 35 is already almost pushing it, it took me quite a while to discover which characters I liked best, since I had to test out all of them, and then look at some vids to look at those character's general playstyles. But more characters could still be fun, long as it's a reasonable amount, (absolutely nowhere over 50, preferably not even close, ~40?)
I think they should make it a little bit more balanced over all.... When I can 10 stock a level 9 with Snake, Snake is OP, and my opponent is quite the opposite. Oh, that's another thing, I was just thinking the other day that an extremely hard CPU would be fun, for when online play is unavailable, or maybe some other reason. I don't mean a CPU with even faster inhuman reflexes than they already have at 9, but maybe one that learns substantially, and develops. One that is highly variable; I've honestly found at least 3 ways to near infinite loop level 9's because they always use the exact same move, over, and over, and over again.
No infinites... No tripping.... No stale moves
BETTER WIFI
God. I'm already addicted to smash, but if I could play with real people using a better online system, on par with like Halo 3, Call of Duty, Etc. I would honestly be willing to pay 5 bucks a month, maybe even up to 15 if it was incredible.
Just to make it clear.....
Brawl, I still love you. <3. xD.
