The difference of offline play in Heroes II and Heroes III.

What do you think about the "illogical" behavior of the computer during battles in the second game?

In the second game, the computer has "ironclad" logic. :)
There are some nuances in battles. For example, the tactic of distracting from archers doesn't work. The opponent "stupidly" advances towards the target for destruction.
There's an interesting point that could be called illogical. If there is more than one path to the archers, for example, if the battlefield is crossed by a ravine, then by blocking one of the paths with other troops (not archers), we force the enemy to move along another path, even if it's longer. It's funny when, a little later, we block the other approach to the archers, and the enemy turns around and goes back along the first path that was cleared. :). In this case, the enemy's primary goal is the archers, and other allied units are just an obstacle in their path.
