How to start a 1-turn campaign with Rome on stream

[est Dudus]

So I want to do a 1 turn campaign but when I use the mod line -mod:play_One_Turn -show_err Rome is not in the list.....anyone know how to get this to work?

[_Tartaros_]

thats because the roman 1turn is a seperate.
i´m not familiar with steam, but use the .exe that opens the RSII editor and look for the campaignswitch. If you see the 1turn-option, look for roman1turn. normal 1turn contain all other factions without swap-factions
