I'm actually parting the game from Graal so if anyone has name suggestions, I'll take them :-)
The main server will teach players how to code -- like a storyline tutorial. Will also teach how to upload images and models to use.
Players will get their own worlds where they can use their knowledge to, with ease, make their own 3D MMO.
I've just finished setting up client and server sided variables so I think I'm finished using C++ to code the game (other than possible bugs in the future). Everything else can be done with Lua.
