Didn't see the Iroquois. They are not the best, they are my favorite to play with. In my opinion they are the most flexible civ. Whether you want to go rush iroquois warrior (no iron needed at the very least saving a few turns to find iron and build a mine), go wide (general wooded terrain allowing you to build and "chop" settlers faster then pretty much any other civ, and the longhouse turns any city into a production machine, or go tall using the added production from the longhouse to produce buildings and wonders faster then anyone else, Iroquois does. Not the best civ (that spot is currently reserved for Japan/Mongolia/Babylon/France), its flexibility is unrivaled allowing you to "go with the flow", but still win on Immortal. Try em out, you might like em as much as i do
