You could always try to spread your religion to Arcaea, it would be nice to have some actual competition since the MAE are next to useless.
I've actually thought about it, especially if Arcaea gets that whole empire/vassal-state thing going that I heard about a while back (is that still trying to be done, or given up on?). It's a pretty neat concept, and I would love the "mission field" of the "empire."
However, I'm still just trying to get a decent foothold in my own region and maybe one or two others before I can even dare venture out. Breaking into the Order of the Elders stranglehold on the area is proving brutal purely from a mechanics standpoint. The actual nobles and Order leaders don't even have to oppose me, the game does for them, lol.
