I'm not worried about the models, I would need to recreate them anyways (and get rid of the grey nails syndrome). I'm more worried about the automatic copyright law. I'll put some links at the end of this post.
Copyright does not protect the idea for a game, its name or title, or the method or methods for playing it. Nor does copyright protect any idea, system, method, device, or trademark material involved in developing, merchandising, or playing a game. Once a game has been made public, nothing in the copyright law prevents others from developing another game based on similar principles. Copyright protects only the particular manner of an author’s expression in literary, artistic, or musical form.
TL;DR about what I think about this:
I can create a game with the same name, same controls, etc. Everything that's technical.
The artistic parts of the game are copyright protected by default (story, visual art, music):
-That means I can't implement the story so far (might do a sequel or a side story or a "parody" but that's under the fair use vs derivative work area which is quite murky).
-Probably can't use the looks of the characters, even if some of them are generic looking.
-I can use the music though, because they are not BoN's work.
