Seems nice project if it gets going.
CraftStudio is a multiplayer platform to create games and interactive movies. It's about empowering gamers and blurring the line between playing and creating.
It makes a few trade-offs (a low-poly, pixel-arty look) to allow gamers with no particular experience to:
Create, paint and animate 3D models (characters, objects) out of blocks.
Craft infinite maps (think Minecraft?s creative mode), painting your own blocks to create whatever universe you want.
Give life to their worlds using a visual scripting system.
It?s all real-time, you can collaborate with friends or strangers over the Internet. You can set up your own server or join an existing project.
