Unlike Final Fantasy, Dragon Quest has stayed true to its roots. (Online entries ignored for both series.)
So Dragon Quest is in much better shape than Final Fantasy. Splatoon 2 can certainly beat its predecessor, but Dragon Quest XI is a really tall hurdle, so I'll go with Square-Enix's game. I would already be surprised if Splatoon 2 comes close, despite its added portability.
Legend11 correctly predicted that GTA IV (360+PS3) would outsell SSBB. I was wrong.
