I find that the game system is very flawed. It's rules-heavy as shit, there are rules for stuff like "conversation" and it doesn't provide enough details into stuff like: - What are all the houses/their words/their sigil ? - What are the different types of weapons and armor and how they are different ? (There should be more than 5 armors one can chose from provided he has the money/access to them) - How large is Westeros, what's the current population density, what was the past population density, how many of them are farmers ? How many of them own land ? How many of them reside in cities/village ? How many knight errands does a lord have ? How easy/hard is to arm/sustain an army... etc Thus, the GM needs to have read the ASOIF books a few times and have limited "macro" knowledge about medieval societies. Even so, I found myself disliking the system, you basically need a gentleman's agreements between players to not create "power-fantasy" characters, since the system easily allows for it. Also, even if character creation goes well you still have the problem of leveling up and the constrains that are put around any social interactions. In a game based on a book about intrigue and deception you would think that they wouldn't narrow down conversation to a complex "charisma check", but that is what they do. I would strongly suggest trying to go with a modified version of the Pendragon rules or a home-brewed d20 rule-set rather than sticking to the books.
