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

Leader, honestly explain to me what makes the HD mod better than SOD? I recently tried playing on it... I guess I'm getting old, I'm used to something else, and because of habit - after exchanging troops, for example, the cursor switches to the other hero, and I often run away with the main hero to another area instead of attacking the enemy who gave the troops. Since everything is based on reflexes, there's no time to evaluate. Because of this, I stopped playing through HD. As I see it, there are two advantages to HD: setting up roads (but I don't care about that) and splitting units (which is also not critical). Transferring troops, artifacts, etc., is easier in SOD.
