LOL. That video didn't even have the Melee physics in it yet. Look loosely, at that point it looked like it played closer to Smash 64. So so tired of the Brawl bashing. Don't know why some of you Brawl bashers are so hyped. You'll probably hate Smash4 like you do Brawl.
I have to wonder about this myself. I enjoy all the Smash Bros. games but A LOT of people were vocal about Brawl's gameplay tweaks. Basically, Sora "over-polished" the mechanics and slowed down things a tiny bit, and it rendered the game unplayable for hardcore Melee fans.
For general Smash fans, Brawl was great.
I have a hard time believing that Smash 4 will
feel more like Melee. Unless Sakurai and the development team had taken serious notes about the Melee->Brawl changes and the hardcore fan response, to the point of actually trying to re-create the feel of Melee (as well as replicating Melee's l-canceling, physics exploits, etc.), then the odds are Smash 4 will be a continuation of Brawl or will do its own thing, which will be equally as controversial.
So yeah, people who were lukewarm about Brawl or straight-up disliked the game probably shouldn't even be hyped about Smash 4. For all we know, the next iteration could end up entirely different than all three of its predecessors, especially considering the inclusion of a 3DS version. If you're not in it purely for the fan service, then you should probably keep your expectations in check.
