While some elements of the gameplay can feel repetitive, you still get to use them in fresh ways. It's almost like your mind graduates in terms of the level on which you think of the game. At first, you're into the mowing down enemies mindset, learning your new combos and movesets and figuring out what type of combo attack is the best one for the situation (narrow, wide, distant, all around you, etc) but eventually once that part becomes second nature, your mind moves on to more of a field commander role. As the challenges become more complex and varied and difficult (you'll largely have Adventure Mode to thank for that) you start thinking more about breaking enemy offensive advances (you've killed enemy Stalfos, the enemy is withdrawing!) and learning when you need to be where and just how much your allies can take before they need your assistance. I've never been a fan of the hack-and-slash types, but between the interesting combat challenges, the Zelda paintjob and the rather deep combo mechanics, I would call this game quite enjoyable.
Plus, I'm absolutely looking forward to playing as Skull Kid in February.
