Its a great book for clarifications of the existing rules and to offer suggestions on how to play the game. There isn't anything "New" per say, but rather pulling together alot of bits from the other books so now they make alot more sense. Also the Archtypes are exteamly useful as either bases for characters or stock characters for pick up games. Got a new player, not sure if they are going to remain in your group or for reasons didn't have time to make a character? Just ask them what superhero they like and give them that archtype. Well worth the price.
