I checked out DBGT: Final Bout and tried to sort through all the dumb Dragon Ball narrative and characters. Half this game's characters are Goku, so that makes stuff easier and even dumber! This game was heavily sought after by collectors in PS1 and early PS2 era. US copies were going for $300. There was even an entire bootleg scene making prints of these on Ebay back in the day! It got nuts.
A lot of folks bought Japanese versions of this game and got weird accessories to make it work on an American PS1. Needless to say, there was a lot of effort put in to play this by a lot of folks. So you'd think it be great, right!?
