The AI's strategic thinking is severely lacking.
I set the highest difficulty level in the game just to test it. The most difficult AI for each hero-opponent on the map. And the most difficult map, in my opinion. Of course, all of this is done offline, without connecting to the network.
It's easy to restrict the movement of neighboring opponents by buying additional hero assistants, simply by leading them to the opponent's castle each time. The opponent's hero returns home. As a result, the opponent falls behind in development and becomes easy prey.
Otherwise, it's impossible to win against all of them with these settings... :D
Where do you get these versions of the game, or is it because of Windows 8? My AI is just terrible
