I beat Bravely Default on 3DS the other day. Overall the game is really good, I'd say about 85% of the game is top of the food chain when it comes to JRPGs, great stuff, however the last 15% are a huge let down and it is only because of the characters/story that I pushed through it. I'd reccomend it regardless, but just be prepared for a disappointing last few chapters (the ending is good though, just the chapters themselves are not good).
I then purchased Ghost Recon: Shadow Wars for the 3DS and it really good as well. It's basically Xcom but set in the Ghost Recon universe. It's not quite as in-depth as Xcom, but it is certainly not as frustrating which I think is a good thing.
My 3DS gets so much of my game time, it's my go to system without a doubt, more so than my PS3/PS4/X1/Wii U/PC etc.
