I purchased Resonance of Fate after keeping it on my wishlist for years. The gameplay is absolutely amazing if you can figure out its combat system and enemy weaknesses. It's far from a normal RPG in that you still level up but your stats remain relatively the same, all the real stat modifications come from how well you customize your guns to increase damage, charge times, etc. It can be very difficult in that even basic enemies can bring you to the game over screen if you don't plan your moves correctly.
