When you build something in the open-world sandbox game Minecraft, you can share it with your friends. You can invite people to hang out in your little world of blocks and pigs, or can put your creation on YouTube, to be admired and posted on Kotaku for the world to see.

But you can't sell it. Or build AI and quests around it. Or see your creation implemented into a heavy-duty MMORPG, to be experienced by what could be millions of players around the globe.

That's what Everquest Next Landmark is for. SOE's oddly-titled online game, which will enter alpha on February 28 and closed beta on March 31, is a giant sandbox with a complex, robust set of creation tools and an ambitious goal: to out-Minecraft Minecraft. You can build homes, spaceships, and giant phalluses, then take them to Landmark's store and sell your blueprints to other players. If you can make really awesome things, the folks behind EverQuest Next will take them and use them for the full-fledged MMORPG version of the game, which will be out at some point in the future.

I played a little of Landmark during a meeting in New York City a few weeks ago, and my interest is definitely piqued. The toolset takes some time to learn—I doubt I'll have the patience to make the kind of eye-popping castles and titans that we'll eventually see in the game—but I dug what I've seen so far.
