Adding in a couple others:
Fire Emblem Fates - Yeah, it gets a lot of hate from series veterans, but I really enjoy what I've played of Fates (Finished Birthright, making decent progress in Conquest). I consider it to be a step above Awakening in terms of gameplay mechanics, and while Conquest's story gets a little frustrating with how dumb Corrin is sometimes, I liked Birthright. Some people expect every game to have a super deep flawless story, but I thought Fates was fine in terms of writing. Not the most emotional story ever, sure, but I liked it.
Blaster Master Zero - I just picked this one up today on the Switch, but I know it's also on the 3DS. I've been having a blast with it so far (pun intended). It feels like it'll be a little on the short side, but it's pretty cheap and there's a new hard mode that was recently added in too.
