The game should be better, yes. heres some stuff that should be fixed:
Broly has black hair in normal form(seems like every saiyan has black hair.) he has yellow hair in ss form, blue hair in uss form, yellow hair, larger body and burning of energy in lss form, luss form is right, just increase his body size a bit larger than lss.
fix piccolo model.
i like vegito/gogeta models but gotenks looks the same as them, plz use the elite/league/rebirth/supreme model of gotenks.
13 should have their real forms, check the models of the rigged versions.
cell, bebi should have all their models.
plz add the dragonball radar.
buu needs right models.
add an ss aura, something like the old supreme aura. ask kyuubi[lew] about if you can use his ss aura's or something.
ill add some stuff u should fix if i come up with something.
you call that a ss4? its just a hair fix, wheres his tail? wheres his fur? there is a guy who ade goku models, including ss4 on this site, just go to models and search for goku. use that model instead.
