i hated it until... "But you will only be able to build unique units in cities who they "belonged" to." This could be interesting, but i have a few questions. Independent/Barbarian conquer give anything? What about if rome collapses and i conquer pompeii? What if america collapses (not that i have ever seen it happen)? what if an independent city of egypt takes an independent city of greece? It is these independent/native leaders who will probably give you the most problems, but as long as your restricted to building units in areas they came from, i think it could be fun.
