I agree with chromaticdragon. The main idea in this game is your creativity. The rules are simple so that you can adjust any part of them into a more difficult or easy experience. You can make your own impossible adventures, if you like.Depth? There is if you are creative enough as a storyteller. Replayability? You can change everything from game to game, even make your own characters. But even if you don't the game is different every time.
For me it's a very good game from solo to as many players as you want, simple so everyone can play and also as deep as you can make it yourself.
Still if you don't feel creative and want the game to provide everything for you, it's half as good as I described...
