Despite its continued success in Japan, the Dragon Quest series has never quite found its footing in the global market, unlike the Final Fantasy IP. Much of that has probably to do with Dragon Quest being decidedly Japanese in its art style as well as its comical approach.
For the poll options, I've decided to lump DQII and DQX into Other, because they are (likely) the worst and the MMORPG entry, respectively.
What's your favorite main series Dragon Quest game?
Bonus question: On which platform(s) do you expect the inevitable Dragon Quest XII to release first?
