when it comes to sequels I want familiar faces or else you can't call it a sequel (That's just me though).
So under your theory, every Final Fantasy ever made after the original for the NES isn't truly a Final Fantasy? o.O
Seriously, CC owns, and even if you didn't like certain parts of it, you can't deny it was an awesome game, right? =P
Anyways, CT.... Second RPG I ever played, and it took me a lot to get interested in anything other than FFVI, because FFVI was and still is my favorite RPG. Both of these games, I love them so very much, and they helped me through a hard time in my life. They are my most prized possessions.
CT has everything a gamer could want in an RPG, except for the fact it's so short. It even has a crossdresser! It's a masterpiece.
