a) In the second game, if you repeat the same actions in combat, the scenario remains unchanged. In the third game, there are many variations.
b) In the third game, a hero can cast Direct Damage a maximum of 1-4 times. In the second game, the spell has no limit and continues to work until all mana is used and the hero's turn ends.
c) The combat algorithm used by the computer is different. In the second game, archers are attacked first, then flying units, and then ground units, with the stronger unit being targeted. In the third game, the computer's behavior is more complex: inflicting maximum damage with minimal losses, blocking archers even if they are not attacked, dealing damage to multiple units when possible, etc.
d) In the second game, regardless of the speed of a flying unit, it reaches the opposite side of the battlefield.
e) In the second game, you can block a portal with your hero, which can be very useful in online play. In the third game, a collision and battle occur.
I've added the updates, thank you.
Frankly, I initially wanted to introduce a section on "spells," where I planned to include, among other things, an interesting pattern in the use of Direct Damage. If we gather more information, it will inevitably happen.

I also added an update to point III-K, regarding the three heroes: but there are cases when it was impossible to track the "logic" in the computer's behavior.
What do you think about the "illogical" behavior of the computer during battles in the second game?
