Just my .02$ on this, Arcachon had a unique style, but a lot of that was attached to the way the nobles were and really does transfer very quickly.
One of the problems was that as old players left the types and styles just didn't mesh as much, especially as the Arcachonian method was based around a religion which really had only a few driving personalities behind it.
Given that the religion lives on, that part of the style likely will as well, and as new realms come up they will have new styles of their own and hopefully some of them will be unique and fresh as well. It really does just depend on the work those who run the realms put in, which means it's up to Matt to pick the right people to ensure the realms have a good "flavour". Hell, I'm fairly sure that once Ciann and her wobblies get squared away large chunks of Arcachonian culture (let's be honest, Ulster Kelt) culture will continue to plague the lands.
Don't worry, with any luck Aenelia will end up in a war with C'thonia sooner rather then later (with luck by next spring season).
Though now I am seriously tempted to just move to Cathay and run a coup, but I can't come up with a valid IC reason. Any suggestions?
