New Super Luigi U's tighter levels and somewhat higher difficulty in the context of barely coherent 4-player co-op is an absolute riot and a great way to spend an evening. It's also just an affirmation of everything tired about NSMB as well as what makes it remain great. Like Mario U beside it, Luigi U suffers from formulaic design and its status as one of Nintendo's very first HD titles, but it nonetheless remains a truly solid platformer. Hopefully once Wonder's out we can reevaluate this series for the polished if overly familiar adventures it has in store
