User blog comment:TheRedJr/How A Fan Pushed Super Mario Into A New Dimension With Unreal Engine 4/@comment-24495139-20150701222257

All that video shows is that Unreal 4 is a pretty good engine. All the backgrounds are from precreated demos. The animations are both just from the blueprints system and recreations of the Super Mario 64 animations. That's about as impressive as tracework. The slightly impressive part is the textures for Mario but, it isn't a very good art style. Keeping the video up will probably be good as it's never good to censor things, even if it gives the wrong impression, but he doesn't seem all that talented for Nintendo to consider him an asset
