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

By the way, in the mod, the numbers stopped displaying in the stacks of the enemy hero... Before, it was something like "alo(1-" which was at least understandable :) Now it just says "little," and that's inconvenient because these "little" indicators are different for all translations, and I haven't managed to memorize where each one is...
