how to win?

On this forum, there are always people who claim to have played Heroes for 100,500 years, completed various campaigns, Chronicles, and so on, and believe they have mastered all the intricacies of the game. Perhaps this is true, but the only way to verify this is by comparing their results with those of other players. Some complete a map in 5 months, others in 3, and some in 1, and so on. This is usually where the most interesting discussions begin...

P.S.: LOL
