Simultaneous turn in a turn-based strategy game.

Well, as for the forces, everything is quite clear; Baratorch says plainly that he's interested in HotA, while SoD is viewed as a source of income, and the person wants to get something for their work—there's nothing wrong with that. In principle, SoD is viable even without OH, but its presence will be a pleasant bonus for a player (like me) who plays HotA when there isn't much time for a full game of SoD.
