I don't care a whole lot about the Graal3D server, but I love the idea of being able to develop things in 3D. Sorry to mention another MMO, but Second Life allows its users to work on creating enviornments of their own, as well as objects, characters, and so forth, and has been very successful with that feature. Graal has sort of the same thing going on, but it's also sort of stuck in the same mode it was in 1998, with a few small changes caused by client updates and a new scripting language.
