Quick update:
I'm getting closer to launching the Unity version of the editor, along with the new sample game (will probably launch the game in it's own thread as it's a complete game, albeit a very short one). I've been giving Mixel alpha versions of the editor and he's been helpful with highlighting engine bugs, so I'm feeling pretty confident about finally getting the Unity Editor out there, I may aim for a Christmas day release.
After that, I'll take another look at the Backbone importer to get the port of TOG finished.
Also, check out Mixel's character combat. Technically, Scorpion doesn't support ducking characters out of the box (yet), but as with most things it can be done with clever use of the 'codeblocks' system.
