all comparisons are in regards to budokai 3, current benchmark for dbz games and which is what this game is a remake of.
- minigames between some of the story fights, like trying to catch bubbles in the kai's planet, aren't as lame as "minigame" suggests
- fights are faster and overall the game controls better
- most attacks are cancelable into supers, instead of being usable only after canned combos
- command list shows the property of each move in a combo (juggle, chargeable, unblockable, etc)
- more characters
- new moves (dashing, new hyper mode, secondary throws)
- cutscenes in story mode
- some useless characters like android 19 where removed
- no new stages, according to gamefaqs
- doesn't use the show's soundtrack
- dragon rush removed, though no one used it anyway
- so far, all secondary throws seem to be the same
- no tournament mode - big wtf here
- worse opening i've seen in a dbz game
- doesn't work with hdloader
- hyper mode has been changed so that your character isn't tired after using it and teleporting no longer consumes energy during it. the problem is that you can't fight someone in hyper mode without it, since they can just teleport out of attacks without any cost and only charge attacks/throws can knock them down. you also regain more energy by hitting the opponent in hyper mode, which means if you opponent gets to it before you do, consider yourself fucked
- dashing seems useless so far. it'd be good if you could cancel an attack to dash outside of a super instead of wasting energy to teleport, but i haven't been able to do it so far
- i think the capsule system has changed though i haven't been able to check it out to be sure
