Current Ideas:

1. Scrap Yeuzhi
2. Add in either Illyria or Numidians
3. Add in (yet) more scripting:
a) If Messana is attacked by Rome, Carthage will go to war
b) A the appropriate time a Kart-Hadeshim army will be spawned in Southern Spain, (if the war is not already lost), Iberia, the Arverni and the Aedui will all grant Kart-Hadeshim an Alliance and Military access, this army will follow a script which will move it into Italy
c) The Alliance and Military Access will be recinded in 200BC
4. Add in traits so that Factions far away from the Romans, (Such as Baktria, Arche Seluekia, Ptomelmaics, Pontos, Pahlava etc.) will lock characters and there armies inside their cities (removing all there movement points) until a historically appropriate date, -30 years
5. The Stats of the the Kart-Hadeshim, Macedonians, (Ilyrians), Eperiots and other factions not chosen at this time will be boosted to keep the Romans occupied and lead to a more challenging game.
6. Regional units for some factions will be removed to free model and unit space for Roman (and major opponents) extra units to lead to a more intensive feel

Any other Ideas?
