Roll Call: what version of EB, Difficulty, and why

[Skandinav]

so medium campaign difficulty actually does nothing to slow the AI's expansion?

There is a noticeable difference in the beginning of a new campaign when the AI has yet to build up its economy but this impression is soon replaced by a behaviour very similar if not (nearly) identical to the dreary, endless warring on the Hard setting and as far as I can tell - and I monitor the AI in every turn - settlements change hands as frequently, although through the means of smaller armies.
Rebels besiege settlements on Hard aswell by the way which I have yet to see on Medium.

But as some have pointed out Medium difficulty could be a good choice for a smaller faction, whereas my Medium romani campaign was a failure my swêboz worked pretty well as I restrained my expansion.

Some say that the difficulty are also influenced by which version, BI, RTW or ALEX, of EB you are playing.
