I just beat it yesterday, but now I'm thinking about how obviously rushed it was like this guy being literally the only plot point for a playable character and you see him for like one minute in the game. Like imagine if Dyne from FF7 but even less screen time and less development an that's just one of several characters Barret had a connection to.
FF9 is a good game I enjoyed but I'm not really going to take anyone's shit about how FF7 is overrated or it's just my nostalgia because I actually played it as a kid. The flaws are there because it needed to be out and out of the way for FF10.
