I have a contact from the old Katauri team, who has a contact from the old Nival team. I'll try to find something out as well. I've caught the general excitement.
Isn't there any copyright infringement here with the owners of the third Heroes game?
The fact that it's free probably doesn't violate any copyrights. But there are nuances, for example, that's why they called their project VCMI, and not Heroes 3.6 or something else.
