Adding a new faction?

Hi tehre!
I'm a long-time modder.
Modded over 30 games in these last 5-6 years (from Baldurs Gate to Freelancer, Freespace, Homeworld, War3, Generals, KOTOR, Birthg of the Federation, Armada, etc...)

I wanted to ask if it's possible to add a new faction? I want to add my own country (Croatia) with it's own trops and stuff. I've read around some tutorials and adding new units sounds straightforward enough, but it's new faction that I'm interested in.

Can anyone shed some light on this subject?

Basically, no. I don't think anybody really did that yet ;)
There's a ton of files you need to edit for it to work... And without new models it will looks somewhat similar to the existing factions (well you can re-skin of course).
I think there may be some RTW tutorials around about how to replace a faction, you should maybe check that.

Never was afraid of modding work... too bad nobody done it yet.
Oh well, I'll keep my eyes open in case someone figures out how to do it.

Don't have time to experiment on that myself right now. If nothing else Im ight add a few mercenary units...
