Recommend me a 3DS game

Ghost Trick. I don't care if it's not actually a 3DS game. It'll run on the system and it's AMAZING so you should play it.

Fantasy Life, it's chibi solo WoW.

Ever Oasis gets released in a few days, you can predownload it.

And try to find the Chrono Trigger DS cartridge, it's pretty much the ultimate version.
