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

I tested it today on both my computer and laptop, using the complete version plus beta 12. When saving the game at turn 111 and then loading it after the turn has passed to the next player, the receiving player gets a message saying they have defeated everyone, while the player whose turn it was receives a message saying they have lost and are leaving these lands.
