The gameplay is more or less the same. A few things changed but the feel is more or less the same. The juggles are more flexable though the 3 hit thing is still there. Its more like 3 sets than hits. Well its really hard to nail down to one rule now. Just know You can do a little more.
They took out the push/regen/powerups.
They added the Break which is a fluffy combo breaker. You get 3 a match.
The stage fatalities that should have been in MK:DA are finally here of course. Since they are mid round fatalities they are more like twisted ringouts as far as gameplay goes.
Throws were thankfuly updated. They cant be blocked(the way it should be) and are more natural looking.(Remember Jax's throw?)
Added stage weapons.
Ducking under high attacks is now important.
We have the return of the sigature MK uppercut. Everyone has an uppercut like pop up done by pressing down + 2. Its a suble thing I doubt most noticed. They work better than most things for knocking people into deathtraps and cant be followed by a combo
All in all its the game we all wanted MK:DA to be. Its totaly fantastic.

so the ground game is still the same?? no ground attacks or the ability to stay down??
and no dash or position change move then?
