This level is a pain.
It always turns into the boss, another AI and myself fighting over Europe while the AI that starts down in Eurasia in the south getting super strong.

The boss never seems to head south. so as long I have to start in Briton I'm stuck dealing with him while the southern army grows strong. I know how to circle around and clean up behind him etc, but by the time we meet, he already has Italy and southern Europe and is fairly strong. I can't just clean up behind him with a couple of armies per country. The other northern AI is not much trouble, but either chips away at my strength, or holds north eastern Europe. Either way, I can't hold enough of Europe long enough to get strong and the southern army seems to grow un-offended. He'll eventually win it all.

Suggestions?

When I watch the history, the boss is putting all his armies in northern or central Europe and leaving zero armies in the south, so the southern Ai grows with no resistance. WTF?

Stop trying to battle the boss straight up. Send a stack into the eastern AI territories to 'assassinate' the commander. Then mop up the boss.

The southeastern commander is waaaay down south. At least 30 turns just to get there.

I think Richard is talking about the commander of the first AI you encounter, not the one that starts in Parthia

Nope. The first commander is a nothing. Just a minor distraction. I'm taking about the Parthian commander. Easiest way to win is to 'assassinate' him then mop up his bonuses. Fighting him straight up makes the level FAR harder.

Should be able to reach him in around 25 turns. Then the real fun begins with clones
