Maybe not a well known period of history but how about a kind of Old Testament Total War. Say around the Invasions of the Sea Peoples(have to decide who they were but hey), End of the Egyptian New Kingdom / Myceneans, Introduction of Iron Weapons, Moses, The Trojans, Assyrians, Philistines, Nubians etc etc

not an especially well documented period of history with lots of continuing debate but creative assembly could definitely have a lot of fun with it.
