[Pickles]

Here are the average tier. I treated tier 4 as tier 3 (thanks for changing the report method guys) and assumed the first 5 and Last 5 in lists were tier 1 and 3 respectively.

Tier 1
Abysia
Arcosnuffle
Caelum
Pythium
Vanheim

Tier 2
Atlantis
Ctis
Ermor
Jotunheim
Marignon
Mictlan
R’lyeh

Tier 3
Machaka
Man
Pangaea
Tien Chi
Ulm

Of course this takes no account of settings. I assume that it takes the best theme of any nation.
