Considering that the installation and setup process for Warlords is straightforward: a standard installer, preset options, and a comprehensive description on the website, the issue lies with the user – is it laziness or something else?

As for the rules, it's strange to expect that everything will immediately become clear and understandable upon installing a new game. Like any game, it requires reading the manual, observing the game from the outside, and testing it independently in single-player mode. If there were no differences from Shades of Darkness, why would an add-on be necessary?
Furthermore, it would be beneficial to understand the purpose of the changes made; otherwise, why try Warlords after Shades of Darkness, where everything already works well.
