I'm not sure if the teams that brought us those games have announced any plans for the release of a rome stile mod but i would personally love to see one. That has always been my favorite era of warfare and i still think rome total war was the best total war game to date.
With Sea battles, the expanded map and slots for so many factions seems like all the things the community has been trying to do with games like EB for years.
Plus you could scrap the americas, keep india and move over to china. If you made it so i could take a roman empire and keep moving east or relive Alexander but without turning back i would love you forever.
