Completed ZombieU 100%, now I'm about halfway through NSMBU.
Holy ****ing ****, I've never been more impressed with a system in my 30+ years of gaming. This is the first time I've been able to game in HD (never touched any Sony or Microsoft crap), and My God the graphics are amazing. I did break down a little bit when I finally got to see Mario in full HD. We've come a long way since the NES days.
