What's the slowest you've expanded?

[QuintusSertorius]

We all know about playing the fast game, blitzing your way across the map. This is not that thread, but rather the opposite - about the slowest game you've played.

I pretty much play only migrated-Epeiros campaigns nowadays, trying out various Hellenistic factions that didn't make the original cut in EB1. The most enduring is Pergamon, probably because it only just failed to get in the game in the first place. But the slowest I've done is with the Bosporan Kingdom - I started the game with Pantikapaion and Tanais and spent 15 years - 60 turns - just building my economy and having no army at all, hoping the AI would leave me alone. Given both had stone walls, the Sauromatae did just that, often wandering over, taking a look, then wandering off again. Only then did I take Chersonesos, which I sat on for another 20 turns or so consolidating my gains. I also play in M/M difficulty which helps.

I've got a Pergamon game at around 252BC, but I'm already thinking about going back to an earlier save and doing things more slowly, not moving out of Mysia before 262BC and not taking Nikaia (since it was a rival independent kingdom for most of Pergamon's existence). I think I should also give Krete to KH, rather than keeping hold of it as I did, justifying it as a defector to my little league. I'm already rolling in money with Pergamon alone, after all.

So what's the slowest expansion you've ever managed?
