The intricacies of game mechanics

The AI doesn't analyze objects it can't see, but unexplored territory is attractive to it in itself.

So, it turns out that it "doesn't see" after all?

Furthermore, it's possible that the AI knows the paths to certain key points – enemy towns and heroes.

It's unclear, it might know, or it might not...
I know for sure that it doesn't take into account the defenses that the player can break through. But does it see the entire map at once (but doesn't use the information it gets because it shouldn't), or does it not see it at all?

I haven't researched this aspect in more detail.

That's a shame.
