Buu's Fury is an objectively bad game. It has no gameplay depth -AT ALL- and is so laughably easy there's no real reason to play it. It's better than the other two Legacy of Goku games, but that isn't saying much since the first of those is unplayably bad and the second is at least a functioning game but that's about all. The card battle RPGs are better games.
Can't help but think that Kirran was taking a few shots at Lani & Grant when he was talking about BT3.
I mean, considering these things are probably thoroughly scripted by everyone involved, compared to other content they do you can tell the different, that was probably intentional? Could be wrong there.
