Start on "Hero".

Yes, that's true, but the Veteran difficulty is too easy, and the Hero difficulty is too hardcore. Where is the intermediate level?

Classic AI
Changes the difficulty levels in the game. This mod is ideal for those who find the "Warrior" difficulty too easy, but the "Veteran" difficulty too hard, or who already find the "Veteran" difficulty easy, but are not yet ready to move on to the "Hero" difficulty. The mod author has made it so that on the "Warrior" difficulty, the AI behaves more intelligently than before (it is now called "Apprentice"). He has done the same with "Veteran," which now has two levels: "Master" behaves more intelligently than before, but does not use cheat codes; "Grand Master" behaves no less intelligently than "Master," but also does not shy away from using cheats. On the last difficulty level, "Champion," stronger neutral creatures are generated.
