Yeah, I dunno anything that's not on Garaph.
Even the Dragon Quest Monsters games on 3DS aren't doing 1 million.
I cannot see Dragon Quest Heroes getting anywhere near that.
Even sales around Pirate Warriors might be optimistic.
Keep in mind the 3DS DQM games are just remakes. Joker 3 will show if they can still hit a million or not.
