Simultaneous turn in a turn-based strategy game.

Wouldn't it be easier 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).
