Hegemonia City States is a complete modification of Rome: Total War based on BI. The mod is dedicated to Hellenic history and the wars of the Hellenic people from late 6th century to the Peloponnesian Wars.
This is last version of Hegemonia City States. Launch the installer and install it into "Rome - Total War/BI". The shorcut that the installer has created automatically in your desktop doesn't work. You will have to create a new shorcut of RTW-BI.exe. Then, right-click on it and click on "Properties". Add " -mod:bi/hcs -show_err -nm" in the target line, then click "Ok". Use this new shortcut to launch the mod.
