Project- Influences of Roman military on modern day riot control

[Nathan Ross]

I don't recall there being any "Game of thrones" types games around.

No need, for the Romans at least - they had the real thing: gladiatorial games and prisoners getting hacked to bits as lunchtime entertainment!

highly likely their local culture would have varied far more than it does today

I don't understand this point - what makes you think ancient societies (or even 19th century ones) were more diverse and multicultural than our own? And why do you believe that TV and computer games instill 'order and discipline'?
