Yes, that is the general idea.

I intentionally have chosen 1570 for the beginning of the campaign which allows more reasonable choice ( Switzerland was pretty inactive since the early XVIth century).

It is very good that Epistoliary Richard found the limit is 30 faction slots, 21 was somehow too strict in my opinion.

Anyway unique units will appear in certain regions - Cossacks, Swiss, Czech even Bulgarian or Slavonian and will be available on certain conditions.

I am going to use all hardcoded limits - we will see how many models are possible to us - that limits us more than the number of skins/generally units.
