Have to agree I see allot of similarities in my campaigns. Here's some highlights of what I see with some regularity...

Egg starts into the Seleucids at the latest, turn 10. Allies with Pontus (awesome faction), Parthia joins in for table scraps, and destroy the Seleucids fairly early. This is a very consistent scenario. It's a shame too because if the Seleucids could get a grip, they got great units, rich regions, could eventually make a great adversary. But the axis of Evil don't give them a moment to breathe. Now Egg, arguably already the richest starting nation, become rich times 10. They eventually dominate the East, and it's always a sure bet who your going to run into once you get out there. Same old same ole.

In the Aegean sea area (middle map) I've seen it go in different directions. This is by far the most interesting place on the map for me to watch for several reasons. Macedonia usually beats the Greeks out of the mainland. Actually the Greeks are setup for extinction from day one, and they are always sent that way by someone. Anyone actually seen them do anything? Some games I've seen Brutii wash through the whole area, even before reforms. Other times they hit a brick wall of Macedonians and seem to get nowhere.

Gaul hammers anyone in their way, but usually the Julii just manage to stay alive with the help of Senate armies until some point (reforms?) they get the will to drive into Gaul. I had to help them when I played the Brutii. Britons usually do well, eating into Germania. At some point the Gauls do loose momentum like already noted, probably when their many borders start to heat up at the same time.
