Resonance of Fate has a very unique battle system but it's also a bit unbalanced because you are very likely to get your ass whooped in even regular encounters. Upside is you restart with only a small cost to your money.
It's also composed by Motoi Sakuraba of the Tales Of and Star Ocean series' so you know the music is good.
There's also lots of customization to both outfits (no stats, just aesthetics) and weapons (THIS gives you stats)
