The night club mode is gigantic, probably takes up a majority of the game space. With that said, I'm starting to enjoy it more and more. I personally try and three star each challenge before moving on ie: the glider challenge took me close to 2 hours to perfect but I found myself enjoying it more so than wanting to throw my controller. I know as far as achievements go you don't need to three star everything, but the added challenge, and some are quite difficult, just adds that much more value and time to a rather short but high playability game.
