A Song of Fire and Ice - Concept Review

Ok, so so far I have looked at three of the houses involved in Robert's Rebellion (War of the Usurper). However I'm going to pause at this point until I get a rough idea of what rules we're looking at. So far I've had a sneaky look at conceptual idea for converting:

• Warmaster Ancients
• Saga
• Lion Rampant

I have also had a quick think over what sort of armies to use (using concepts discussed on other forums).

Westerosi - French Medieval Army (More Cavalry for Tyrrell, higher tech levels for Lannister)

Stark - Scot Army

Wildlings - Celts

Greyjoy - Vikings

Martell - Hispanic/Almoravid

Dothraki - Mongol

Obviously this will be dependent on the rule set so DW lets make a decision.
