Thank you very much for the detailed explanation. I get what you said, and agreed with all. People doing fan versions of games should try not to give any chance for the original IP owner to ask for a takedown. Specially if they are doing a new version of the original IP, and they think it might affect their sales. It would be a shame to take down a project like this, because all of the hard work put in to it, and for what I seen so far it is a good fan project.
That said, what I'm doing is not a fan project per se, is more like a remake for modern computers of Warcraft 1 and 2, but seeing this opens possibilities for me to create maybe new fan campains and stories. I'm doing it because Blizzard has said publicly that they will not do a remake/remastered version of Warcraft 1 or 2, and I just want to play those games in modern computers without DosBox and with somewhat modern standars for RTSs. I know it's not very logical, specially because there are others projects (wargus project here http://wargus.github.io/) and remakes of these games on the internet, but the main reason I'm doing it is because I think I will learn a lot (also the nostalgia of doing one of my first games I played). If in the end I can't publish it (I would always publish it for free) or I receive a takedown notice, well, the project will remains with me. In that case I'll decide what to do with the graphics and logos and trademark names, and maybe create a whole new game, I don't know.
Let's see how it goes.
