I left out Dokapon Kingdom, which seems like good times. Still, I'm going to assume no one else has any objections, and agrees 100% with my list. 
Oh, and Monster Lair.

A Mario Party clone with a twist, Dokapon Kingdom is a board game in which up to four players are given a mission by their king. However, players are encouraged to screw the others over. There are far more branching paths in this game than Mario Party, letting players double back if they so wish. This game also has many RPG elements. Players who land on a combat space, at which point the game becomes an RPG (your performance depends on what class you selected, what items you've equipped, etc.). Players can purchase or find equipment as they go along, or go on mini-quests to earn more gold. Overall, it sounds like a fairly deep and enjoyable hybrid. Recently confirmed as being localized, I haven't been able to find any release date for it.

An intriguing DS title, Master of the Monster Lair involves building your own dungeon for the express purpose of luring as many baddies into it as you can. Once they're there, you hunt them down and destroy them. It releases in December.
