1. No troop-building facilities, other than town watch on "foreign soil".
2. No mercs. Ok, if senate gives you one.
3. Always enslave pop. Exept with Carthage = pop ext.
4. Never chase routers.
5. Only one army offensively when at war.
6. Always besiege until one turn before surrender.
7. Ally with all facs and let THEM breake the treaty.
8. Always offer ceasefire + traderights after capturing one enemy city thus rendering me a lot of cash and outbleeding my opponent.
9. When given a stupid assignment by senate to capture some far off settlement I do so and sell it back to what ever roman fac is closest to it.
10. I´m more prune to conquer, stop, build, conquer and always tries to get my enemies into protectorates.
11. I keep bands of velites, some 200, scattered around the countryside to take care of rebels and farm "men of the hour", it´s really effective and 200 velites can actually take care of well over a thousand brigands if use well.
12. My build order is happiness, order, money and last troop-related. Remember: "We Romans never seek war", he he ;)
