What's a long good DS game?

[MaverickZer0]

The whole Mana series that I've played has been rather good. I should toss Fire Emblem in there while I'm at it. Just because it's a series doesn't mean the games are really related. They stand alone quite well.

I've heard good things about both ZX and Shooting Star or whatever they're calling the Battle Network spinoff in English. I'd say better things about ZX because my opinion of that series isn't as tainted by the 'but they ended the old old one too soon!' as it is with the other.

Castlevania's another good choice if you somehow haven't played any of those yet. Castlevania as a series is excellent.
