I agree with TA, I don't think custom characters fit the Yakuza games.... at least not the main story! What would be cool is a 'Let's make a fighter' mini-game like in Y4, where you could build your own guy, then train him to fight in the underground arenas.
Yeah, they hacked a put in Haruka/the T-Set girls in the place of Kiryu, Saejima etc, it's a funny watch.
NeoGAF is boycotting the game, because they think this is 'cut content' because Sega didn't want the West to have 'Strong female characters'
