It's not that I'm not interested, perse, but I'm not familiar with Kingmaker and I'm too many games already, it probably wouldn't be a good idea to join yet another...
Kingmaker is a sandbox-style AP that takes players from level 1 to level 20ish. It takes place in an area known as "The Stolen Lands." Players are granted a charter by the Swordlords of Restov to tame the savage lands of the wild beasts, vicious ruffians and neighboring kingdoms, and, ultimately, forge a new kingdom of their own from the fertile ground.
There's a lot of other stuff in it, but the most basic part of it is clear the baddies and make your own kingdom.
so I could play my Viking godhi that I only got to play two sessions of (still 1st level) warpriest class.. and it was the exact same rule, nothing homebrew. We were supposed to do Rise of the runelorrds AP
