Hi.I wanna do something like a chosable tech tree,but idk how.Let me give u an example:
let's say that you have a city,and you have a church as a building,where you can research 2 types of religions,Pagan and God.If you choose pagan you will be able to do some pagan specific researches,and not be able to make the God research for the whole game.You can aswell construct more churches,and still not be able to research God.
Is that possible without triggers and stuff?
and if not,how can i do something like this.
