If you want to play as Rome then I would highly recommend building two warriors for exploration/attacking barbarians at the beginning - and then just settlers in Rome and all your new cities until you can build no more for whatever reason (other civs - no good sights etc.). If you can master this strategy, by 0AD you should have 12 cities and from there get a decent defence up and running - but focus mainly on building temples, cathedrals and most importantly as many wonders as you can - enjoy! P.S. Try not to get rushed - the one weakness of this otherwise great strategy!
