And you'll understand) In VoGE there was an option - launch "as SoD", meaning with minimal differences from the original game. Otherwise: HotA is configured (if there are any settings at all) without Caribbean exoticism, with ordinary jars/artifacts/necro. Essentially like SoD.

Um... no. I think this should be obvious already. The main concept of the project is a continuation of the original add-on line. Did you see an option in SoD to "make everything as in RoE"? And, although the previous point is sufficient, still: another core concept is gameplay uniformity. That's why we try to avoid any checkboxes altogether. Heterogeneity is introduced only by various map/template conditions, but certainly not by a gameplay checkbox.
