Mostly I just remember (fondly) the big supporting character calling me "Gov" all the time and going, "COR BLIMEY!"
Haha Yangus is cool, yes.
Also, apparenly, in the PS2 game you also cannot:
Spoiler:
Recruit Red and the Monster Arena guy to your party. Red is mandatory, but Morrie isn't. I took Yangus out of the main party because he is slow and the later you get in the game he becomes less useful. Dunno if I'm gonna get Morrie, though. Angelo, Jessica, Red and Hero seem all fine as a team.
