Implicating dragon_quest_numeral to dragon_quest.
Reason: For IV, V, and VI, they're marketed as a trilogy, which strikes me as being overarchingly relevant to each other, and thus the series tag. DQV's standing implication has "If it belongs to a specific game, it automatically belongs to the series" tacked onto it, though from FF discussion, the current stance is only if there's enough carryover, right (in which ase DFF seems fitting, eh?)?
'Concerns': Any of the DQ Monsters games. I'm very out of the loop on DQ stuff, so...
