I recently updated the [Aoc] Medieval Kingdoms Units mod. Before it wasn't really playable, but now it definitely is! Here are some of the changes:

Old Units removed (there are now only MKTW units)
Unit balancing fixed
Unit upkeeps lowered
Some faction names and banners changed
Units not being able to be recruited from upgraded barracks fixed

Check it out!
