I agree they need to get rid of those nasty tribal languages in the game, (all those Roman soldier speaking the language of the Latin tribes, and the fact that all the game materials, at least in my copy, ar printed in some bizzare degraded hodgepodge of that and the language of some northern Germanic tribes)
Side Note: Swahili is Not a tribal language it extends across much of Africa. Tribal Languages, pretty much by definition are spoken by One tribe, I seriously doubt there's any one on these forums that knows a truly Tribal Language.
