Well there is 6 kingdoms per server, each kingdom has 12 duchies, each duchy has 24 counties.
There is no set number of towns per county. anywhere between 1 and 5 is the expectation on the forums. And that one might just be the county capitol with the counts house and the required support structures.
and there is 4 servers
most of the counties will likely be NPC for the foreseeable future.
But just for the sake of discussion let's say they all were PC controlled right now.
That would be 24 kingdoms, 72 duchies, and 1,728 counties who could all have recruitment threads,
and let's say there wasn't any other towns besides the county and higher capitols so that we don't have to factor mayor\town recruitment in since that is a number that is impossible to tie down since the # of cities per county is not fixed amount like the rest.
that is almost 2,000 potential recruitment threads there just for "regions"
before you factor in schools, guilds, and associations in to the mix.
So in short, there is and will always be a metric shit ton of them.
as others have said, your best bet is to skim thru the threads and find some that on paper sound good fit \ peak your interest.
Then join those groups discord\teams speak\forum\whatever and get to know the people until you found the group that you mesh with.
