We now got the basic techdemo projects up and running, they are called Zario ( for python) and Zua for Lua. Just the basic loading a level and not crashing so far but it will form the basis for future development so a step forward anyway :). Next for me is some work on the Lua script interface, more work on making something playable of Zua and then a lot of work on the editor.
Ohh and I need to play Borderlands a little to =).
