Have Rome Total War?
If you have the great strategy game Rome Total War, I suggest that you download the Rome Total Realism mod. The mod expands the campaign map to include Scotland and India, adds several factions and has a number of unit changes.
Instead of being able to recruit anything anywhere, there is an area-of-recruitment function, that let you recruit local units. This is handy, so you can supplement your faction's strengths. If you are the Greek Cities, you can recruit swordsman and non-crappy cavalry to supplement your hoplites built in the homeland. In addition, almost all of the units have new models that are extremely well done as a mod. At the least, this mod will sustain you until the new expansion pack comes out.
