YAPO is a game modification that adds a new party mode to Mount & Blade II with its own unique set of rules. You can set rules for each path and even split up the upgrades into different decisions.

This mod isn't just for Mount & Blade II players but also for those who love the game, are passionate about it, or just like to play Mount & Blade II in a different way.

You can create your own path in YAPO, choose the order in which you want to upgrade your troops, and set how many days you want to reserve gold and the rules for an upgrade. YAPO allows you to create an upgrade path that automatically updates your troops based on the day of the week.

You can also create your own decision, set a player decision for each path, and choose how many players will be involved in each decision. The player that chooses the best path gets to take all the glory, while the other players get to experience the journey as a contributor.

It is possible to set rules to be applied to every path you choose, to only certain paths, or to only one player. You can also set rules to be applied to all of your troops. You can split up the upgrades into as many decisions as you want, allowing you to take part in every decision that is made.
