// 01 Why
Heroes 3 nights with friends
Heroes of Might and Magic III is still played at LAN parties, often with Horn of the Abyss. Custom maps get passed around on USB sticks, and a long multiplayer game is saved on one PC.
With SyncCrate one PC hosts and the others match it. Maps and saves are compared by content and only the differences are copied.

Good to know
- GOG Complete edition. Horn of the Abyss needs the Complete edition, not Steam's HD Edition. SyncCrate looks in the usual GOG folders; point it at the game folder once if yours is elsewhere.
- The game and HotA aren't copied. Only maps and saves.
