I can add my two cents... but it's a rather sad story.
Just the other day, I found and downloaded the English version 1.1, not the one where the computer drags around dwarves and orcs. And I was even thinking of playing on it... but something terrible happened - the Battle Grounds (that is, the arenas where battles take place) have a different structure in these versions (Buka 1.1 and Original 1.1). Specifically, the trees, craters, and other obstacles are located in different places on the map. This is a very important point, as the majority of battles are won by using the terrain to your advantage.
But why did you download the English version when you have a licensed disc from Buka?
It's obvious that a licensed product, which in this case is the 1.1 version from Buka, cannot be simply downloaded like its English counterpart.
We hold Tournaments not on pirated copies, but exclusively on licensed products!
However, in Heroes 1, it is sometimes very difficult to determine which version the game was played on, and without a very thorough check, it is practically impossible to do so!
But I hope that you will not promote this fact, but play within the established rules.
I repeat: if, upon checking saves, we detect inappropriate actions by the computer and find out that the player was not playing on the version specified in the rules, their save will be annulled, and the player's reputation on the forum will be negative!
