Hello everyone,,
Some of the better examples would be, I think, Mount & Blade Warband with the Brytenwalda mod, for a good historical depiction of the 7th century British isles. Another one that come to mind are the Paradox games like Crusader kings, Hearts of Iron and Europa Universalis series. Some titles in the Total War series were accurate I think, especially Shogun 2: Total War. The Europa Barbarorum mod for Rome: Total War is one of the greatest historical games I've ever seen. Does /askhistorians know any other good ones, either popular or lesser known?
