I took all of Italy lat night except for the toe and unfortunately it had more to do with AI failures than my strategy. The Brutii still have massive armies in the Balkans but failed or were slow to either ferry them across to relieve their cities or land behind my line in the middle of the peninsula. I built a fort on the border of Dalmatia? and Venice and this slows them down and allows me to defend against their attacks in the open. I also have assassins taking out their captains (and family members if I'm lucky) and diplomats bribing little stacks.
I exterminate the cities I capture and knock down there temples and build my own. This makes cash not a problem but bribing Romans is expensive so i do it sparingly.
My tactics vs. the Roman armies rely on strategic movement to put my self in a threatening position so they will attack me. (Of course this army has the best troops and leader). The AI often attacks without combing groups before hand so I can often defeat them in detail. Even a unified army has trouble keeping together when I send out missile troops, light chariots and slingers, to harass their flanks. Often they send their cv chasing after them which is fine because they won't be around to flank my rush.
As the Romans advance I position my infantry in one line for the charge. If I have a druid I start him chanting and select the inf group and have them give their war cry. While they're pumping themselves up I send my barbarian cv/heavy chariots along the sidelines so to speak to be in position to double back on the Roman line or pesky skirmishers. By this time my boys are ready to go so I double click the whole group/line to a point behind the enemy line. The Roman units defend in depth in an open grid pattern so my swordsman rush smashes into and around their units. Their is a lot of feverous clicking as I send those units not engaged into the rear or flanks of a nearby unit or the enemy general if he's close. I then pick the best targets for my nonmissile cv and that usually does it. My leader I might sent in to mop up but usually I keep him close.
Again, this tactic assumes you have experienced chosen swordsmen with upgrades as the core of your army with a balance your most experienced inf chariots and barb cv. Non missile cv is essential because your swordsman can't rundown their skirmishers and they will decimate your lightly armed inf. Heavy chariots are decent flank shock troops but are too slow to be effective chasing skirmishers. I use head hurlers as well and send them in behind the rush to where resistance is strongest use them to crack the line.
Pretty soon its mop up time. The above tactics will work on the offensive but you really have to use your skirmishes to pull their formations apart. Also maneuver your inf and try to catch their line out of formation when you charge.
