Ugh there's too many... think first to mention is Final Fantasy Dissidia. I wanted it as an early Birthday present, I got it... well, 2 weeks after or so and I don't play it anymore <_< I hate it that the closer I get to the end of something, the more I lose interest...
Well, aside from Dissidia, there is more. Much more.
-Cockfighting Society Mystery Dungeon 2 (ok completed, but there is a shitton after the game to do)
-Zelda Phantom Hourglass

-Disgea DS
-Chrono Trigger
-Mario&Luigi Partners in Time
-Final Fantasy XII (want to complete it with all mobs done, so this'll take a while)
-Ratchet&Clank Gladiator
