======CraftStudio======
Looks pretty interesting! **CraftStudio** is an online, real-time collaborative game making thing. An example given had one player modelling a dragon and another painting it at the same time. It appears to be voxel-based, and quite //[[game:Minecraft]]//-looking, but there seems to be flexibility there.
