Simultaneous turn in a turn-based strategy game.

Wouldn't it be simpler to create a mod that removes HotA heroes, objects, and castles? That is, make a HotA mod for SoD in which all bonuses like new portals remain, but all objects that SoD players dislike are removed.
2Grizvald: It seems to me that this option is easier to implement by a third-party developer or one of the modders (for example, you could try contacting Wizard).

In the new template editor, it will be possible to disable new castles, new objects, and new artifacts.
