Huge fan of the Avatar setting and Magpie did an exceptional job at adapting it. I'm happy that they went with PBTA as the engine, rather than something like d20, because it really lets you focus on telling fun stories. The combat system can be a little tricky, but I've grown to like it and think it does a good job at adapting the types of fights we see in the show for a tabletop narrative. The combat cards are super useful, I hope they release a PNP version sometime (I bought the cards).
