Since I'm sure a lot of changes are going to be made eventually, and removing Briton and Numidia will be a lot of work, I'm not going to do this yet. I'm at the point where I can zip the installer and upload it, so any changes from here on will have to wait for a patch. Easier that way anyway, because changing those two factions will go along with the unit naming scheme. I'm sure there will be many suggested changes once you see this, so it can all be done at once.
I've successfully 'installed' this on a fresh copy of RTW patched to v1.5, but it was missing a few things so I had to find that stuff and get it in the installer......the date change kinda messed me up, but it was worth it, and resolved now. I'll let you all know when it's up.
