As in no Mario, Zelda, Pokemon, Fire Emblem, Smash Bros. or anything even remotely owned by Nintendo in some way. I'd say my favorite non-Nintendo 3DS title would be Rune Factory 4. There's just so much to do in the game and I feel like it combines RPG with farming simulation near flawlessly. It's probably one of the best non-Nintendo RPGs on 3DS honestly. So what is your favorite non-Nintendo 3DS game?
