Eh, I traded my PSP in shortly after realizing how much Monster Hunter sucked, and how just about every game on the damned thing had terrible controls.
Though the one game I did like was Final Fantasy Tactics: War of the Lions, and this is coming from someone who is a noted Final fantasy and JRPG hater.
I guess I would call it Disgaea, but with a more serious storyline, and MUCH less need to grind. Though if you like grinding (you freak), then you still can, just be aware that monster enemies (NOT human enemies) level with you.
