Well... I will play sometimes, but I'll mostly play Brawl.
Why?
Mainly just because Brawl will most likely have the advanced techs, since 99% of techs aren't glitches. Take for example, wavedashing. They programmed it so you keep your momentum from the airdodge to the ground, just like in real life. We then just jump and airdodge really really quickly. ASAP, actually, which is just before you jump. L-canceling was programmed, since they saw that Z-canceling helped with the tourney scene, which gives popularity to Smash, which gets more sales. Also, SHFFLing is just SHing (intentional, look at the AI which sometimes does it, and look at Marth's classic mode completion video, he does a short hop with a nair), L-canceling, which is intentional, and FFing, which as always been with us. Oh yeah, and with the ken combo, I doubt they'd wanna piss him off. Marth will most likely be in, since he is so freaking popular that removing him would not be good. Marth would probably be an unlockable, though... but he will most likely be in.
Oh, and they'll most likely improve Bowser. Or I shall destroy them. >:D
And, online would keep me going. I'd still gotta play Melee sometimes though, so yes, I'd still play....
(P.S. If brawl has online, after a couple months, since they will most likely have a skill ranking system, like with MKDS did a decent version, if they make a good ranking system, and actually apply it (why didn't you apply MSC's ranking system? ><
, then you wouldn't have to worry about advanced techs much, you could just play how you want, so that would satisfy that issue... Let's just hope they do that, so I can enjoy my advanced techs while people don't have to bother with them.......)
P.S. I said no fact here, just opinion. So don't think I'm saying fact, it's all just opinion.
Now excuse me, I'm gonna play Melee some more.
