I looked at the Blender Game Engine years ago, I don't know if that is the same as BDX. Wasn't quite my thing. I also am not a fan of Java anymore and only use it if I have to. As a scripting language it might work well, but I've had to support a lot of Java apps that were not games and over time that has made me not a fan of Java. :) I'd use it if that was what I needed to learn.

I still appreciate your comment though, as I didn't make this just for me. So some people might truly benefit from knowing about BDX so thank you for sharing it.
