Super Mario Land: Minecraft Edition
Yes, some people have too much time on their hands, and we're glad they do.
We've yet to dip our toes into Minecraft, and for good reason. The world building game requires weeks and months of a person's time.
That said, there are plenty of folks who can happily invest the man hours necessary to churn out incredible looking creations. Case in point, this Super Mario Land tribute.
Definitely impressive, and not easy by any means. Watch the making of video to see how it all came together.
As for Minecraft...yeah...we'd have to forego all contact with the outside world.
