Is is one of the worst mainline Final Fantasy games? Yeah, I think so. Is it a terrible game not worth playing? Absolutely not if you're a big fan of the series and already played quite a few of them. It tried to do something very interesting with the leveling system that I can respect, it just unfortunately didn't quite hit the mark. While this version made the game trivially easy (unless it was normal difficulty and I've just played this game enough to get around easily) I think that's the best way to experience the game since it lets you skip most of the grinding in the original release and speed through aggressively okay to bad dungeon design to experience a story that was rather ahead of its time, which for me personally was probably the best story in FF until FF5 came out. Dawn of Souls technically has an extra mode for a bit more content, but personally I don't think it's worth playing a whole version for unless you're already planning on playing the game on GBA, in which case go for it.
