While it was fun, and the gx are descent. It was EXTREMELY easy. Only got to level 72, and I beat the game. Didn't take long at all. And that Dark Blade skill, 999 damage, makes any boss a joke. For the grinder, its average, gets a bit "too" tedious.
I give it a 7/10 for average story, easy game play, descent gx, and too short.
