Good day, I wanted to buy the old Heroes of Might and Magic III, but it turns out that sales have been suspended. By the way, it would be good to add this fact here in the topic and update the header!
Now you can only buy the "new" HD version based on The Restoration of Erathia, which costs almost 1000 rubles.
It's a problem, comrades.
Who can share their experience? I'm not a newbie, I know where to download it, etc. The question is different: are there any problems for those who use a non-digital copy of the game? Not just in terms of functionality, but about the possibility of playing online with other players, including those who have a license.
