Alright. I know I barely post here but this game is too amazing to keep quiet about. Essentially the game is a sandbox MMO where you create structures with big "voxels" or 3D tiles. You can create and destroy them at will and now you can do it with friends in real time. A handful of us over at TIG played together and made a moon, a ship, a huge maze with an observation deck, an impressive house with a vaulted ceiling and other sweet stuff. Link to some screenshots.
It's still free, but probably won't be for long, though right now during the alpha pre-orders are half-off and they allow you to texture your own character. So... that's the end of my "sell".
Though, sadly now the server is offline and even worse we had a griefer come in just as we were running climbing races to the top of my tree. There's nothing we could do since the kick/ban features are still pretty limited, and he successfully destroyed most of what we worked on the entire afternoon. Anyway, if someone wants to start up a GWJ server, post it up and we'll create awesome out of thin air!
