Unplayable Factions (BI)

[Vlad The Impaler]

What do we know about them?
which of them can be made playable?is there any patch that could enable them?
How about the faction that will emerge later?
I know that romano-british faction could emerge if Londominium and another town is conquered but thats all
How about the Slavs and the orher factions?

Take a look at the RTR site, they're doing a mod for BI now. Apparently every faction that appears can be made playable but there's a limit on the actual number that can be made activate at any one time, something like that.

well i know RTR site but i didnt find much there except the fact that guys are working and this is great,they have awesome mods.
right now i'm interested in RTW vanilla and how i could trigger the factions that are emerging later.
