Yet another series announced to be returning at E3 is Firefly’s Stronghold series. Stronghold: Warlords transplants the RTS game of European (and Arabic) castle building and siege-ing to the east, with Japan, Korea, China and other nations represented. Warlords is also expanding the game outwards, and adding a ‘light’ grand strategy layer, letting players boss around the titular warlords; AI controlled minor factions that can work for or against you. While not quite as sprawling as a Total War game or Sins Of A Solar Empire, it’s an interesting way to expand the design. See how the warlords work in the trailer below.
