It'll play significant role. That's all I can say for now. After all the events lead to Hussite wars few years down the road which were a massive religious unrest.
Thanks a lot for the reply. I probably worded it in the worst way possible because I didn't know one of the devs was answering questions here and didn't expect a reply, can I try again?
My question was more regarding what role the institution and Catholicism itself will play by and large in the setting. The most historical middle-ages rpg we have so far is Darklands(which had, ironically, an exaggerated version of the period where every myth and superstition was true). Religion was central to everything in medieval life and that game did a pretty good job at expressing that down to a T, both the good and the bad. Arnold Hendricks(the developer) was an historian and that had a large part to do with it.
I ask because I am somewhat of a medieval history buff and that is the main reason why I am interested in this game. Historicity is a big selling point to me, I hate how most fiction about the medieval period is some bullshit propagating the "dark ages myth" that every single medievalist hates.
Also: How will the player interact with the Church? What role does religion and religious rites play in the game? What role do churches, cathedrals and universities play in the game? I have seem a lot about fighting, peasantry and village life, crafts, but very little about that. These things were central to life in every medieval city and Darklands did a good job at presenting that.
