I'm buying 3DS in 5 days

Bravely Default is solid. Fantasy Life is also solid if you don't mind grinding that is not necessarily of the combat type, but it's a really good game to have for those times when you're stuck in the interminable line at the DMV.

If you don't mind playing DS games, Radiant Historia is excellent and very, very highly recommended.

Zero Escape is something I'd recommend with reservations. The first two games are excellent, but playing those means you'll be compelled (yes, compelled) to play the third, which is a great and pricey lesson in how much life can truly disappoint you.
