This mod has been out more than 2 years and only now have I got the chance to play around with the mod that has diplomacy in it. The mod is called Perisno and the game just ate my time just like that.
Warband itself wasn’t meant to hold players hand and the mod made things a little more difficult with the added amount of money for.. well… basically everything. Maintaining a large army is expensive, buying gear is expensive and so on and so forth. Creating your own Kingdom will require hours into the game before you are ready enough to get hacked on by other nations.
Perisno mod throws players into this land of Perisno with major factions duking it out for territories. That is where you come in, like the standard warband game, and make a difference in the lands either by becoming a puppet or as a ruler.
Perisno added some awesome looking mounts too. Even the Lore is worth checking it out.
I say, why not go back to the old game and play it again differently. The download for Perisno mod is here.
