The World Ends With You
I also greatly enjoyed:
- Disgaea DS
- Anything with "Dragon Quest" in the title (haven't gotten around to DQV yet, though I'm sure I'll like that one, too)
- Etrian Odyssey (not an easy game, though)
- Front Mission
- Mario & Luigi: Partners in Time (like DQV, Bowser's Inside Story is in the ol' backlog)
- The Rune Factory games (great if you like Harvest Moon, otherwise this might be an acquired taste)
