I apologize for my laziness for not reading waht everyone's talking about, but i can't find another thread to talk about this. I got this info from the new ign videos.
BRAWL IS JUST LIKE SSB64!!!!
Almost EVERYONE is floaty,
They have their own entrance again,
And check this out,
you remember in 64 when you get hit sometimes at low percentages and you go spiral straight up and down like 2 feet, Well just look at mario in Meta Knight Ship (Off-Screen HD), 00:54. That didn't ever happen in melee but DID happen in 64.
Here's somehting else noticeable, Their DI is also taken from 64.
Everyone can DI quite dramatically, JUST like in 64.
A crap load of game mechanics are taken from 64 and put into brawl!
I think that brawl is going VERY similar to 64, which i'm happy about.
