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

I've already explained, and besides, it's obvious. I won't write anything more detailed so as not to offend anyone.

Please provide a link to your explanations.

Counting moves down to the second? - yes, that's cool :)))
I saw it for the first time at the championship in Kyiv when Vik did it - I almost went crazy - it takes so long - I now understand why everyone wants to play in 6-8-10 minutes. And no one knows how to play in 1-2 minutes.
This is real disrespect for the opponent - to prolong the game with meticulous calculations of every single move.

HD is positioned as a game accelerator, but in reality, after its release, we increase the turn time to 10 minutes in tournaments (and at one time, everyone played for 4 minutes, and it was like that for a long time).
