I personally loved FF9. I liked the characters ( with the exception of Quina ) and thought the music was wonderful. FF9 is my 2nd favorite with FF8 at #1. SOme things ARE annoying about the game though such as:

1. Kuja's thong
2. Quina
3. Trance system

As for Necron, yeah that was weird. I kinda liked it though, I defeat Kuja and then Necron shows up. Completely unexpected! I like his battle theme too.

Yeah, some things are annoying, but I loved the game. It had WAY better characters than FF7. Each character had a distinct and charming personality and thats what made the game enjoyable for me.
