Trisection is my favorite Battle Theme. I also really like Ovelia's theme and the sadder alternate version.

He's definitely one of if not my favorite composer(s). He tends to use a lot of the same instruments over the course of the same work, but FFXII, Valkyria Chronicles I & II, FFTactics and Tactics Ogre could any day of the week be my 5 favorite RPGs and he's a big reason why.
