I can probably wip somthing up this weekend or next week, just so people can get an idea of how they work, their implemented right now but very half hazardly in a way thats not very user friendly, for example they dont project the players territory yet and so can be reclaimed by gia after a while unless you build a town centre next to them, another issue is their units taking up player pop, these are simple fixes that can be implemented when i have time   Here's the current messy basic version with a bunch of bugs in if you want to try, they might not spawn every game, so reveal the map when playing if you want to test them, they currently dont create an attacking army but the rest is there. vassal_settlements.7z

Is there an early release for the mod?

Thanks! that sounds ultra cool!

Right now, vassals spawn as gia structures on the map randomly at the start of a match. they can be captured and then become player controlled, once captured they activate their ai, produce workers and a patrolling army, and then produce a small fighting force to attack your enemies. This does mean you can technicaly control their units, but the basic ai implemented will order them back after, usually within 5 seconds of you giving their units orders. This is a vassal i captured, and as you can see its harvesting basic resources and its army is patrolling its territory.   Edit: i will probbaly have them produce a patrolling army when gia controlled, its already there but ive deactivated this for now for testing purposes but it adds a fight before claiming the vassal prize.   Ideally once i have more time im looking into having these spawn as seperate players once captured, they can still use this basic ai i have in place but it would stop players from acidently selecitng their units.
