Not sure if you live in America, or if you care for te series but adventure time is 3ds is coming out in October.
Other than that, I'd say , ocarina , Icarus, ghost recon was ok ish, yeah
i am desperately hoping that it will be a free roaming game, a bit like zelda mabye, where you can visit all the kingdoms to do lots of sidequests!
also i think it would be cool if there was dlc (or even *gasp*) free episodes to watch.
God I can't wait!
unfortunately there is little, or no, information.
so far all we really know is that the game will have both a ds and a 3ds version.
and that it should be coming out around autumn,
at least this is one game that we wont have to worry about being localized, if anything it might not get to japan.
(unless there are many fans)
here are a couple of links that you might find interesting!
