This is one of the coolest things I've seen in a long time. It's a totally free, totally customisable fighting game engine made by a guy who worked on the Tekken series. I've always wanted to make a console-style fighting game and this framework makes that possible. I've been talking to the EF-12 creator, Masahiro Onoguchi, and he's a super cool guy. He needed some help with translation for some of his documentation and I volunteered. Having a lot of fun learning how his engine works. Pretty amazing stuff.
Here's a link to the official U.S. download for EF-12 if anyone is interested:
You can get content into EF-12 via Maya, Softimage or Blender. Basically, anything that can generate a Collada file should work.
