Thanks Pyg, you're the best.
Finished nation assignment now, and am very proud to say everyone got one of his three picks.
Helheim and Atlantis remain unclaimed at the moment. Anyone having a change of heart and deciding either of these nations sound cooler than the one they got (and picked in the first place) feel free to switch. Also, anyone who hasn't signed up yet, but feels the urge to jump in, can claim either nation as their own.
Final paragraph for those wondering how I arrived at the final list. (Also known as: "Why did he get nation X while I'm stuck with sucky Y")
Short answer: Because I said so! Now shut up and play!
Longer answer: My first priority was to get everyone one of their 3 picks, rather than get as many players as possible their first pick. This does mean there will be a few instances where player A will see his first pick played by a player B who picked that nation only second or third, because player A was the only one(or one of the few) who picked the nation they picked second or third and ended up with.
If that explanation is a bit obscure just read the short answer again.
Or if you are really, really desperate to know, PM me, and I'll see if I can remember the reasoning. No guarantees there though, it was a bit of a puzzle to get everyone one of their picks.
