Ugh, it's so great. The different combat types, all the hidden characters to find, the Iron *fucking* Chef mini-game with a wild-ass narrative of it's own that the game doesn't even tell you about...I stumbled on it the second time around, I never even noticed it beating the game the first time!
I think the castle mechanic especially - the way it keeps expanding and all the characters you recruit add something to the base - is such an untapped idea for JRPG's and games like it.
Yeah that was the coolest part of the game, the base mechanic.
