A modification (or “mod”), for the ones who don’t know, makes use of the tools of existing games to create, rarely, entirely new things (total conversions), or most often to enhance the game itself, add content, fix bugs and so on.
Rise of a King is not a total modification, as it takes place in Warband “Native” world, but from the beginning is way better than native because of the many other mods I’ve integrated. M&B modding community is awesome, and a treasure for a new modder.
My own effort is explained here on the forums, pretty extensively, and it seems to have been received well. The mod has not been released yet.
CURRENTLY ON HOLD, WAITING FOR M&B BANNERLORD
