aka: Caesar I
Caesar can be linked with Cohort II, a strategy game focused on battles and also set during the Ancient Roman era. When linked, the battles in Caesar can be played through the Cohort II game. However, because Cohort II was released later then Caesar, this feature is only available in re-releases.
In the late 90s — early 2000s, the full DOS version of Caesar was available as a free download from Impressions Games' website. The download link was removed from the official game page on Sierra's website sometime in late 2002. Vivendi Universal Games later confirmed that Caesar is not redistributable freeware.
