Battle Master its low fantasy medieval strategy game you start out in a "duchy"(a realm inside an overall kingdom) lots of social interaction, you can hire Units (infantry,archers,mixed infantry/archers,calvary,special units) your character and its unit are separate(you can raise your character to be just about anything including trader,infiltrator,bureaucrat,priest, ect...) its very in-depth game letting you almost literally do almost anything depending on the realm you join(be it a monarchy,democracy,or any of the governmental types that exist IRL letting you vote or earn rank based on that government type) also none of the governments are preset its all player based and you can even rebel to overthrow whoever is in charge, VERY team based game battles are usually held with 10-50+ people commanding any number of their own troops in formation on either side of the battle.. better yet just visit the site and read the manual/faq its too much to go into for a forum ^.^
