I've just finished a campaign in Rome Total War with one of the Roman factions, the house of Julii to be precise. I took over the whole world and destroyed all the enemy factions since I thought you could play as any factions you defeated. I tried to start a campaign yesterday but for some reason only the three Roman factions were available 
Anyone know if there's anything I can do to unlock the others?
Thanks
