Brawl - EPIC!
Elite beat agents- one of my favorite ds games out there, hard at first but once you get used to it, you're addicted to the game and you can't put it down
Twilight princess - I enjoyed it
Layton - I like solving the puzzles in it and the crazy storyline that the game has in it.
MKWii / Galaxy( tie! )can't choose between these games... =/
