Love these ideas. To be honest, out of all of these, I'd like to see more accurate ragdoll physics the most. I don't want to see Fallout style ragdolls or anything like that, I just want entities to show their death animation right when they die, not a few seconds after. Additionally, yeah, there should be a jump feature. Vaulting should be adapted into a feature where you can climb over fences or something, but you should be able to jump right over a tiny fence almost instantly. Nice job on the ideas.
