I started playing it last week. So far, it has been a great experience. Although I am the only player who read the books, all others became interested and asked me to borrow the books to read. As far as I can see, the system works well, although I disagree in some design choices, especially related to the One Power, which, by the rules, is derived from your abilities bonuses. Our GM ruled the creation of a seventh ability, Power, which is used to evaulate the Strenght in One Power of the channellers and to give bonus to resist the One Power. I liked this house rule, although we didn't have much time to actually test it.
