The first parts really should have it too as they do change between his forms/who he's fighting. I'd put it down to not knowing where specific lines are used since JP doesn't change as drastically.
Oculolingus I feel like it would have been dirtier if Yamcha actually said "girl." Him saying "robot" just reminds of that FilthyFrank video where he pretends to fuck a laptop.
In another universe this game sell millions and got a part 2 and 3 with the majin buu saga,movies and maybe until the battle of gods support from there the 4 part would have become like xenoverse with a bunch of dlc cash grab
Is it possible that you could get all the Drama Scenes as well? I've been interested in them. Also, if you have this on XBOX360, I'd love to play with you.
