I like this a lot more than the existing Mario sets, which are really more like playsets then a typical Lego set. I think this concept of recreating levels from famous video games is one of those ideas that you don't think of until it gets announced and then it is so obvious in retrospect you wonder why you never thought of it.
Do something like this for Ocarina of Time with micro-versions of some of the dungeons from that game and I'm pre-ordering it.
