I hate rigging shoulders 
And that FPS don’t simulate body damage the original soldier of fortune done a good job but for some reason these big corps can’t figure it out for there so called modern game engines.
@jonathandone, I don’t really care for rigging anything… 
And I haven’t even tried BGE yet due to the fact that you have to be a decent modeler first.
I hate going to bed. (Sound just like a little kid, don’t I?)
