The AI's strategic thinking suffers greatly. I set the highest difficulty level in the game just for fun. The most challenging AI for each hero-opponent on the map, and what I consider the most difficult map. Naturally, all of this was done without an internet connection, in offline mode. Neighboring opponents can easily be restricted in their movement by purchasing additional hero-assistants, simply by leading them to the opponent's castle each time. The hero-opponent returns home. This allows you to gain an advantage in development, and eventually, the opponent becomes easy prey. Otherwise, it's impossible to win with these settings... :D
