Do you lose/gain honour when concluding peace then? As provinces change hands automatically now, I assume you don't lose honour when you capture a province.
You can gain honor from handing out titles to your existing vassals, or by granting land/titles to courtiers or ronin retinue commanders.
I like the new way of paying for buildings. Is this going to be in CK2 as well?
I don't know, depends on how many ideas they want to steal from us...
