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

baratorch, the standard sound for turn transitions is used both for generic system messages and when an opponent needs to move during their turn, which forces you to either run around aimlessly (very bad) or simply play without sound and check periodically (also bad). If system messages were eliminated (which would be better) or a different sound was assigned to the start of a turn (and the old sound was muted, perhaps even manually), this problem wouldn't exist for many players who have things to do outside of the game.
