Basically I would jizz my pants over the following mods/games:
1 - Improved and expanded Brytenwalda/more early Anglo-Saxon invasion stuff
2 - Charlemagne era mod
3 - Kievan Rus/Swedish viking era mod with map extending from Scandinavia to Byzantium
4 - Late Anglo-Saxon era focusing on King Cnute's North Sea Empire
5 - Germanic migration period focusing on arrival of Franks and other tribes at the Roman border
I can't explain why but I am just fascinated by history set between 400 and 1100 AD. I've been to Renaissance fairs and they're extremely fun but I don't really care about the late-medieval and Renaissance eras. World War II has always interested me too, along with the Age of Exploration and the Enlightenment. I was obsessed with Rome when I was younger. I still love the early/High Middle Ages but nothing compares to the Dark Ages!
