One of the great things about Minecraft is the sandbox-style play scheme that allows the freedom to do things like construct Lord of the Rings' Mines of Moria in extreme detail over the course of a year. That might be the most impressive Minecraft geek-out we've ever seen, but it's far from the only one.

From the world of The Lord of the Rings to the world of Star Trek, there are plenty of sci-fi structures just waiting to be re-created in everyone's favorite block-building game, so we've combed the 'net for 25 of the best.

Of course, many of these creations are far too detailed to be contained in a single image, so click on the caption to see more angles and even video of some (not all) of these nerdtastic constructions.
