Mario Maker is the overall best exclusive of 2015 and I do not see any exclusive topping it
I was very skeptical about Mario Maker but after after a bit of convincing I decided to pick it up last night and I am glad I did. It is a very impressive game and I have played many, many very neat levels. I name Mario Maker the best exclusive of 2015 inching out Bloodborne by half a centimeter
Anyone skeptial of this game I highl recommend you to give it a shot. It does (almost) everything right and I would say there are more "good" levels than bad ones. Just wanted to make this post for anyone else who was on the fence about it, if you enjoy 2D Mario you are going to enjoy Mario Maker.
