Well, this is my opinion. (I was a rabid FFTA fan, so yeah.)
YES. Well, yeah, pretty much. New visuals, new classes (some jobs you have to unlock via missions, but that's okay with me.) more missions,etc. Benched members get AP too now.
The only bad things are the laws and maybe the storyline. I like the "story" so far though. The laws like "No knockback" and "No harming seeqs/females/etc" anger me though. :< I didn't have too much trouble though. Half the fun is finding loopholes :>
Oh, also, I like the bazaar system. :> I don't have to grind to get unlockable weapons anymore, but some people don't liek it.
