Sorry but i'm a bit confused. I played many hundreds of hours of PW on warband and did plenty or roleplaying there. I'm curious as to if this is a whole new module or if this is like a group or server within an existing Persistent type mod.
Unless i'm wrong, this was a group in PW for warband but now you are developing a new mod in Bannerlord?
Well, good luck to you. Anything PW, PK or RP related has me really excited. I can't help much with any coding, I just have a bit of scene making experience.
