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

It would be worth elaborating on.

But why are logs saved in ICQ? It's the same here. There are often situations where a controversial situation is resolved in the in-game chat, and then everyone tries to take credit.
For example, a game situation where one player passes through an area without defeating the guards. He writes in the chat. The opponent replies that it's not a big deal. And after the match, he demands victory.

A more valuable feature would be something else. When you press a button, the last messages from the chat would be displayed. Because they disappear very quickly, and you don't always have time to read them.
