I think it's a fucking disgrace that they managed to not include the Seleucids in a Roman era game. I am still seriously pissed off and I have half a mind of pirating the entire deal because apparently it is accepted to cut half the content from the base game and sell the rest of the stuff for additional money as DLC. The base faction selection is a fucking disgrace. It's like releasing Barcelona as additonal DLC for FIFA.
In any case, I am a complete phalanx slut. Nothing is more majestic than a spear wall lawnmowing through enemy mobs. Basically any successor kingdom, of which there are shamefully few, but still a bunch. Makedon will be my first play I guess, or Epeiros so I can shit on the Romans earlier. Unlike a lot of people I tend to dislike playing Romans and I usually enjoy messing them up. I like Pontus as well but without the Seleucids it will just be weird, hopefully Pontus gets phalanxes as well as cataphracts.
