Problem is it can get really boring after you achieve it. Expanding into North Africa just doesn't feel right, and neither does anexing Gaul (albeit runing raids does feel good).
With a faction like that, I prefer to do what "feels right" (i.e unite the peninsula and build a rich and secure position) then stop. Ignore the victory conditions stated in the game, just do what's right for your people.

Then maybe break some Gallic heads if it's fun... ;)

This will give you long enough to experience the miltary gameplay, without getting into the grind of long distance conquest and assimilation over dirt roads.
