Hi Azarias,

1. Best estimate I can give you is > 50%.

2. The game supports DMs and players. DMs are always hard to come by so we'll be lucky if we have more than a few to be honest. As for players, given the number of users that are registered (in the thousands), I can't imagine not having at least 20 players regularly. It could be a lot more. I have no way of really knowing until we launch and let players get on.

3. Ideally, yes players will join houses from the actual setting and actually run them so that we can build on the kind of political intrigue Martin introduced in A Game of Thrones. This is something we'll coordinate through the forums. One caveat is that to play a noble (like lord of a house) players really need to have good roleplaying skills and solid understanding of the setting (like have read the books). The more prominent the house, the more important this becomes.
