[ANNOUNCEMENT] Heroes 3: World Tournament - an add-on for tournament games.

Then you don't quite understand the specifics of the mod – some things (damage dealers in water, slowdown on the second floor, Armageddon on the fifth) are hardcoded into the executable and cannot be changed with options or checkboxes, and what is this "SoD" you're talking about?

I'm talking about things that can be changed with settings. Changes hardcoded into the executable are not even up for discussion; there's a manual for studying them. Most people are afraid of new things, and when they sit down to play the mod for the first time, they get scared by the number of settings, or rather, they don't even sit down, but when they just see what they're going to face: some banks, experiments, classes, etc. – all these off-putting things can be easily pushed back for later, without scaring players during their first encounter.
And in general, a separate manual for the mod should be created – describing only those changes compared to "Shades of Darkness" that will remain when the mod is maximally configured to be like "Shades of Darkness" as an option. Experience, classes, etc., should be hidden under a spoiler as a secondary element.
