I am a bit loaded with RPs right now so I am unsure if I could join. Thankfully this game seems to have a healthy following so I wouldn't worry. Aside from that my faction would have two things that might complicate my participation. One the map emphatising island nations and thus my group of nomads having troubles with that. The other is that I would need to border other players for a more enjoyable roleplay experience. So in this aspect I'd actually wait till more claims are made even if I join.
So I'll be awaiting to what kind of nations others manage to come up with.
