Thanks, you are a Jack of all trades, but luckily it was easy enough to find on this venerable forum (link to Chick Parabola). For a hobby designer like me this is a good read :-)
That’s a hard one once CDR and HCV are getting thrown at you ;-)
To switch sides and smash the Roman rubble is a worthy undertaking for one who’s already conquered the ancient world as Rome. You can also do it in Hegemony, though, and if you haven’t yet tried the Iberia Campaign Pack in the steam workshop, then you’ll surely find it interesting enough, basically polished to DLC-level, and I hear the author is still working to add even more content to it.
