It's a voxel based sandbox world like minecraft, where you have to harvest for resources that allow you to build all kinds of things with voxels.
But unlike minecraft you can change the shape of the voxels as well.
This allows for things like curves, slopes etc. Which allows you to make structures like this:
The game is still in closed beta.
Next updates caves and water will be added for example.
And eventually programmable NPC's, quest creation tools etc will be coming too.
The best structures made in landmark will even be added to the new Everquest game EQnext (which looks very promising as well, but that's for another thread)
Any other TLers playing this?
