HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Yes, indeed, this is possible in the case of a town trader; it's strange that no one reported this earlier in the three years that Heroes of Might and Magic Online has existed.

In this regard, another question has worried me. If players in Heroes of Might and Magic Online each play their own game and only exchange information at the end of their turn, how is it that they don't find the same heroes in the tavern? It would be logical to assume that the hero pool is simply divided in half. If so, is the division algorithm known? Is it possible to understand which heroes I can hire and which I cannot?
