It's really what you are looking for.
If you want an easy ride, or a beginner, or don't want a super-sized ecomany or even just to attack Barberian cultures, Julii are best.
If you want to have a challenging game against volcainoes, earthquakes and Cathage and Eygptions, love gold armoured troops, brilliant navies as well as haveing to trapse miles between aftican provences, Scipii are for you.
Brutii, on the other hand, have a way into greece, the largest moneymakeing area in RTW, do battle agaisnt the Phalanxes and phalagnites and have massive battles from the word go (Whenever I seige thermon, no less than 3 full flag greek armies attack me on M/m mode), as well as haveing the experiance bonus from Mars's temple, then go play with them.
Troop wise they are all the sameexcept that the Julii are better- they have the best colour scheme !P.S: Welcome to the forums
And I shall go Softly into the Night Taking my Dreams As will You
