re: #478 Feline Fearless Leader
Though there are some simulators that are very video game like and are used. But beyond a certain point they are nothing like the common games. (And I think the vehicle and aircraft simulators are more likely since limited sight lines are much more common as compared to the all-round views and inputs an infantryman would be dealing with.)
Unsurprisingly, the most effective training one might get on a computer game is the one in which the real-world user is already insulated from the outside world by machinery and technology. Flight simulators are halfway there but for the need to use kinesthetic feeling and a heck of a flexible neck.
Train simulators are probably the current state of the art.
