Doesn't it seem strange that no one else has the same outcome?

Yes, it does seem strange, just like it does to you. And I wrote about my theories on this in my walkthrough.

Indeed, this person is very lucky to have a computer that always produces the same battles.

Regarding the battle in that recording – yes! The battle map was always the same. There were other battles with unchanging battle maps as well. But not all!

and then the person writes: "Vitaly (21:29:59 9/08/2008) and then had to generate it." "Strange," it turns out it's not always the same? Or is it always the same only when needed? And when it's not needed, it's not always the same. It's interesting, isn't it? Please decide, is it always the same or not?

Let me explain. In that recording, it was always the same. By "generate," I mean the process of creating the battle map. And since the battle map was always the same, the process boiled down to going through the ideal tree of options. Well, I didn't achieve the ideal, but what was achieved was enough.
For example, round 1. Core griffons attack, unicorns blind. The turn passes to the snipers.
There are 4 branches of development in the tree of options: snipers wait, snipers attack, snipers go into defense, snipers retreat.
At the same time, if the snipers, for example, retreat and receive a morale boost, then it would always be like that. If the snipers attack and receive a luck bonus, then it would always be like that. If the snipers go into defense, and after that, the Sorcerer casts Slow, then it would always be like that. That is, the tree of options (or the battle map, as I call it) is always constant.

well, and when you decide, then decide why for everyone else always everything is the opposite?

I explained the constancy of the tree of options by the fact that the battle was run under the OS Windows 2000, and also that the conservatory is its internal structure. And when I was writing this opinion, I also pointed out this when I posted the description, and also that my opinion does not claim to be correct. I am willing to figure out together why this sometimes happens. But listening to your offensive accusations is extremely unpleasant.
