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

By the way, is it possible to implement a feature similar to World of Tanks, where hovering the cursor over an art asset displays its name? Because I, for example, often confuse the spyglass with the telescope, and a couple of other art assets, and I don't seem to be the only one; this can sometimes be quite important.
