I have a 30 minute train ride to and from work every day and I use that time to play DS. I've been doing this for the last 6 years so I'm searching for more DS games I haven't played. What are your favorite DS games? Recommend me some!

Please note that I have played most of the popular games so don't bother recommending any Pokemon, Mario, Zelda, Castlevania, Final Fantasy, Kingdom Hearts, Professor Layton, Phoenix Wright, or Dragon Quest games. I know about those. I want some hidden gems!

For those who are also looking for a hidden gem of a DS game I highly recommend Radiant Historia. It plays like an oldschool Square SNES RPG. In fact if I were to compare this to any other game it would be Chrono Trigger, which is high praise from me since I consider CT one of the top 5 games of all time.
