As CA has so frequently said, Rome 2 will start with 8 playable factions...
And with 6 already announced, and so many various factions so far missing out, DLC will be inevitable.
So if a popular faction is missed out, do you think that it was planned as a way for as many people as possible to buy that faction as DLC...? Because there is little point bringing out a little, weak faction as Dlc as few will be interested in buying it!?
A bit of a side note but personally, I quite like the look of the starting line up, ESPECIALLY the Iceni and Suebi ... (Tin hat now on, ready for barrage of hate )
Food for thought...
