Playing with Julii as ONLY Roman Family

[ShapolioKhan]

hi masters of RTW moding :)

i've been trying to play as Julii asonly Roman faction in the game but i ve failed all the time.

Its the list what i've done;

1)edited descr_strat and deleted other roman family members from the text file and gave their cities to rebels, gave Julii cities to rebels as well, set Rome as the capital and the only city for Julii.(made other cities villages and deleted all their buildings cuz i wanna build them by myself)
2)Placed Julii family members and spy/diplomat in the borders of Latium.
3)Placed rebel soldiers to the cities i gave them.
4)edited descr_regions file and swaped default culture to julii as other romans wont be in the game.

what do you tihnk? whats wrong or missing?
please help me to DO IT!!

many thanks...

PS:in descr_regions.txt

region tag
; settlement tag
; default culture tag
; map RGB value
; comma-seperated resource list
; triumph point value
; base farm level
Means;

reion name
Settlement name
we'll write default culture here (romans_julii in italic cities)
RGB ????????
understood
ok
ok.
what is RGB value? maybe this can be my mistake?
