DHD makes more sense to me. "Duck Hunt" (jointly) in this context is an adjective and feels unnatural to refer to a character, a noun, as such. The character is a dog, "Duck Hunt" is a modifier that describes what type of dog he is. So I like DHD. I don't care that the duck is there with him (for whatever reason), the duck is assisting him, an auxiliary really. I think the 'character' is principally the dog.
Well, in your context, yes, Duck Hunt could be seen as an adjective, potentially. Or a Title, as if it were Duck Hunt's Dog, the Dog from Duck Hunt.
I don't agree that it is the 'entirety of Duck Hunt' as the character, but it certainly IS the dog and the duck, toghether. We just got used to the idea of it being the dog alone, the duck is clearly an immense part of it, and is much more personified than the Pikmin or Luma's, being a legitimate animal, and it seems inhumane to not include them as part of the character, to just think of them as assisting objects.
I still have two more pages of this thread to read; but
if Banjo and Kazooie were in this game, it would be a crime to NOT consider Kazooie an equal member of the team even if you primarily control Banjo.
I don't think it makes sense to think that the 'game known as Duck Hunt' is the the character. Sure, other characters appear to attack and assist, but how many people insist on calling Olimar 'Olimar and Pikmin', or better yet, why did we never call the Pokemon Trainer 'Pokemon Red Version'?
Pokemon is exceptionally well known, and the Trainer, much like Villager, is an avatar character; he has a generic title for that exact reason.

Iceclimber was the Japanese name for the Iceclimbers, after the game. It was simply because it could easily be changed into a subjective noun that would be more stomachable to American audiences that we were given 'Ice Climbers.'
Even then it was in reference to the game, they weren't 'NANA AND POPO.'
