Wiggin is the Win32(/Linux) Intuitive Graphical Game-oriented Interpreter with Networking. Still in development. It will blow away little text mode universal game engines like Megazeux when it's released. Will have C-like script language, client-server networking, and a powerful debug mode. Written in C++, probably going to be GPL'ed. Things like FF3 clones and 8-player networked games of SC2 melee will be doable inside Wiggin.
