question about the engine

I have a question:

In EB the map has got homeland and expansion territories for each faction, which is a nice and realistic thing. The only problem I have is, that as the game advances the player even isn't able to recruit own troops in former expansion territories, which are, let's say after 50 or 100 years, that much settled by own faction population, that it would justify own faction troops. Does the game engine of RTW and M2TW allow something like this or not?

Just wondered because if f.e. Rome conquers whole Italian peninsula they still would be able to recruit f.e. around 50 B.C. (game time) only Celtic troops in the northern area and Hoplites in the south of Italia.

Probably the game engine doesn't allow something more realistic, but I just wanted to ask anyway :beam:

Reforms. Of which there are plenty of in EB.

Rome is a strange case, they can't recruit factional troops outside their homeland until the marian reform. And they can't even train them in bononia and patavium, before the polybian reform.

AFAIK the other factions can recruit factional troops everywhere from the start (still limited by government, of course)

There are too many 'what-ifs' to have every faction expand their recruitment everywhere. Besides, most factions didn't convert the natives to their culture and style of fighting as the Romans did.
