Thanks for the feedback about copyright! I've updated my post to remove that because its not really relevant to the goal of this post. This is more of a personal project than anything else. I'm really not worried about copyright, as Heroes of Might and Magic III open source remake on github is a thing. But regardless, copyright issues are not the things I want to talk about, I really just want feedback on any other thing I've mentiioned.
As for why the post is in the lounge, to me the motivation was, "Hey, I've been thinking about doing this thing for a while, I wonder what people think about it". And I felt like general discussion was a good place for something like that. I'll move it to wherever it needs to be. Thanks for the responses so far!
