Well on the way now. Romans are still being a pain though 
Point taken with Nicomedia, I've weakened the garrison now. I've already given Byzantion to the Greek Cities, didn't seem to have any serious effects on the local powers in the last couple of playtests.
Already considering that. I was thinking it should be Celtic in nature and comprise the Belgae, Britons (using their faction slot), Lusitanni, Illyrians, Insubres, and Bastarnae. I know those aren't all Celtic, but they all historically had at least substantial Celtic influence, so I think that's good enough.
Excellent 
Should we start a new thread about the greek/barbarian superfactions (or ressurect one of the old ones)?? I'll let you get the ball rolling if you want.
I've thought about that a lot, especially given CC and Antonov's plans. However, I just can't see my way clear to making them a faction when they never really had expansionist goals in our map area. If we make them a faction, then theoretically at some point they're going to conquer a substantial fraction of the map, and I'd feel silly if people started talking about their epic Carthaginian-Mauryan battle at the gates of Jerusalem.
Fair enough. It was more an idea of trying to keep Bactria from getting way too powerful by making them fight for some of them. Incidently, since you mention Jerusalem - maybe we could introduce a few middle eastern "rebels" instead? I say this because the Ptolemaic Empire only have the Seleucids to worry about and hence take proper advantage of the situation and eventually grow enourmous - plenty of examples out there. If you could move Dhofar and move it to Ireland too (see below) we can then make them a persistant pest that they can't always ignore. Carthage won't be too affected by this becuase the culture is exactly the same, so revolts won't happen.
One more idea: I have a spare region sitting around right now (the one north of Denmark). I could easily add that to Ireland, put cliffs around the whole place and deep forest down the middle, then add each side to one of the superfactions. That way, they could never be killed off. Population growth would have to be kept artificially low, and recruitment there would have to be prevented so the AI didn't build huge armies it couldn't use
Sounds good to me. This is practically terra incognita, yeh? You could take a few of the peripheral provinces away and have them as areas for "tara" and "sveaby" freeing up some more regions for whatever else (What I mean is that e.g. the Aden area is given to one of these incognita regions, and Aden can then be used elsewhere). Er, how does this work with a human player? there won't be any problems in that regard?
EDIT:
I knew it!! Publius Cornelius Scipio was the problem! I put him in Rome, and created a new general (Publius Valerius Laevinus - who else?). Laevinus attacks Pyrrhus on the first turn, victory is mine!! huzzah!! We now have our own battle of Heracleia without the need for script
.
Quintus comes down still, and then attacks Pyrrhus when he besieges Corfinium (usually turn 3). Rhegium is also typically lost to Pyrrhus too.
On a final note, look what Bactria have done
