Adds a provincial campaign that makes all the emergent factions fully functional. Other changes have been made. Goths can build ports, Romano British legionaries and warlords are as strong as their Empire counterparts. Romano British can recruit bucelarii
Go to your rome total war folder then BI/data.
Backup your files, then replace them with the included files. Put the emergent_campaign folder in the world/maps/campaign folder. If you are unable to play as the East and West Roman Rebels, you haven't done anything wrong, I had that problem too.
Send me a message at twcenter (JPHILP!) if you have any problems.
