Casimir will need a State Religion, otherwise he would be unfairly advantaged in not having to deal with Piety. Sure, there were Aqueducts still in use, but the majority of them had become obsolete and/or damaged beyond repair (and IIRC the knowledge of how to construct Aqueducts was lost in the Dark Ages, but maybe that sounds a bit fanciful). Bathhouses accomplish the same goal, now, and, at least, fill out the Medicine tech. I actually really love the idea of the Granaries requiring Wheat. Not so much the pre-placed Wheat though . I'll have to ponder. If I were to add that functionality to Granaries, I could certainly pre-place the Wheat myself. Conversely, perhaps moving production could require Stone. That said, you shouldn't heed the vanilla policy trees. They were certainly have to be replaced. Further that said, it is a big change, and as Jan points could, could become too much of a distraction from the goals of the scenario. I opted to replace the Circus Maximus as the Happiness NW with the Winter Palace, because obviously building the Circus Maximus as a medieval state is rude. So it does free up the icon. That said, the Hippodrome was built way before the scenario begins and thus would have to be pre-placed - and Byzantium already starts wtih Hagia Sophia and the Parthenon (maybe Halicarnassus, too, can't remember). Excellent. I'll throw some Jews into Thessalonica and Spain at the beginning of the scenario. Thanks. I considered using H&P, but I opted not too. It would convolute the scenario too much, I feel, and I really would rather the mod only contain my stuff - with which I'm more familiar and in a better position to bugfix and adapt. I'd personally like to develop my own Health mod, if it were not for that it had already been done and I've already go far more interesting things to develop. That said, the Black Death shall certainly be an event.
