Reign of kings is a medieval based crafter/ builder based game that applies physics and a feudal system by  allowing anyone to attack, claim, and defend the King's throne. The King and his minions can do what kings do best...raise taxes and keep the plebs in check. you can create factions in game and those in it will be immune from taxation. Unlike rust, this game doesn't take away your homes, towers, gates, and castles....but the Trebuchets you build certainly can. Craft yourself armor, weapons including ranged, and large siege equipment. Tear your foes limb from limb, cage, whip, torture, drag, decapitate, or simply hang them. (shhh. keep a sharp stone in your....back pocket....yeah) to escape the ropes.
You can create characters with body morphing for custom looks. The more people, the crazier the game becomes. It would be sick to see you guys warring against each other and it would even be awesome to see a terrible king and kingsguard. I would recommend adding lore to 3 or 4 guilds and getting everyone into this game.
