Monetization of the game "Heroes of Might and Magic 2, 3, ..."

And one more thing. Everything related to the development of Heroes of Might and Magic III: fixing game bugs, developing an HD mod, creating an online lobby with simultaneous turns, developing fan-made versions of the game, etc. – all of this is completely outside the legal framework. In essence, it's all illegal.
The game is not open-source and freely available. The game is protected by copyright and other rights. And any manipulation of it cannot be legalized in any way.
