Aiko’s Choice is a stand alone expansion for the long running real-time tactics game Shadow Tactics: Blades of the Shogun. It continues the heroes’ story, but doesn’t add much to the real-time tactics formula. If you are itching for more this is it, but Aiko’s Choice won’t be bringing in any new fans.
