13th Age is a game I've really enjoyed running, though I haven't had the chance to try it as a player. It does a great job at combining narrative and gamist elements without bogging down into bloat. Some of the concepts seem a bit heavy-handed at first, but when you get past the moderate learning curve, they become very easily internalised. I've read comments online that there aren't many viable character builds. Personally I haven't run into that problem yet, so we'll see. In any case, if you're looking for a game with excellent combat and a powerful narrative system, 13th Age is worth taking a look at.
