PCG:Creative Assembly are experimenting with ways to keep the game interesting when your power as a faction has reached critical mass. The clean-up phase has always been a weakness of the series, the point in the game where you can’t be stopped, and the road to victory looks a lot like clicking ‘auto resolve’ over and over again. Part of this will be an expanded reputation system where your deeds throughout the entire campaign are remembered: brutality towards one enemy will be factored in by the others you might face, meaning that you’ll face increasingly violent opposition even from enemies who you otherwise outnumber, or alliances of necessity formed in the face of your rolling war machine. Likewise, internal politics can lead to your faction facing outright civil war when power vacuums form. It all sounds very appropriate to the period. The Romans had a bit of a problem with uppity generals crossing important rivers, don’t you know.
