That's cool info that only you, as the game maker, needs to know. If you had just released James as a comic book, also because "you wanted to use those graphics, never really mind the story", we would also have spotted a huge difference between James and MacFarlane. The audience doesn't get to see that side of the story, and for all we knew, James in Neverland was a good example of the best you could do.
And know we see Dread Mac Farlane. Do realize, please, how much you'd potentially injured your image because you just "wanted to make a game with those graphics" - all we know is there's a huge difference between those games, and without that extra info which only you need to know, people just assume it's because you got a hell of a lot better.
