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

Well, the list of differences between Heroes of Might and Magic and Might and Magic is a completely different matter. And whether playing single-player or multiple online matches, there were no crashes. I couldn't have a better opinion. You're trying to prove to me that Heroes of Might and Magic is better than Might and Magic, when all I said was that there were no crashes in the original game.
