A THREAD FOR NEWCOMERS!

Hello, I would like to know: What determines the final score of the game (the one that is written in the leaderboard)? Is there a mod where you can choose which spells to learn, meaning you enter the town and instead of spells being automatically assigned, you can choose them individually? It often happens that there are good spells in the spellbook (e.g., Explosion and Resurrection), you enter the castle, and you end up with something like Raise Dead, or "Berserk" is replaced with "Sacrifice." Heroes 3: Complete Collection doesn't open properly after minimizing: it launches for a couple of seconds and then minimizes again. What should I do? Are there any expansions with a more intelligent AI, to make the game more challenging? Is anyone working on increasing the AI's skill level in "Heroes 3"?
