I’m not so sure about all the “stuff” inside the game – anything from the Build Menu. I think (I repeat – I think. . . .just my opinion now) it would unbalance the game. With Happiness, Food, Cost, etc. But maybe items could be requested to the Devs and then perhaps added in to a Player’s Item DLC. This way it would be a bit more “controlled and balanced”.
But to be able to have the ability to build maps and then fit them in to scenarios that would in turn be knitted in to a campaign. Yes! Most definitely yes! Let us have that PLEASE!!!!
