Sorry, No_Know, doesn’t wash.
If I read your responses correctly, what you suggest is that a video game can enhance your reflexes and prepare you mentally for the vicissitudes of confrontation.
To think a thing is not to do a thing.
To know the timing of pressing the jump button on a game does not prepare you to understand or control your own jumping ability. The only thing that will do that for you is to physically train jumping. Your mind may say “jump now, forward and to the right, raising your legs at least a foot and a half off the ground to avoid that leg sweep!”, but if your body has not performed such a jump sufficent times to be proficient, your muscles will not respond as desired. The jump in your mind will not ocurr in the real world. The timing of the mind is not the timing of the body.
Again, the idea that watching a video game character perform a specific counter against a specific attack will enhance a person’s ability to execute such an attack or counter is in error. In a game, you see things in the third person, from an observer’s angle. The environment is stylized, the ambiance and pacing set by the program. The contact is not felt, because the contact is not real. The exchange cannot be experienced, again because it is not real. It is all only barely in the mind, and not at all in the body. To watch someone drive is not the same as driving. Even if the viewpoint was first person, the sensory inputs are drastically limited, the reactions without consequence.
To say that watching a martial arts vid game character allows a person to absorb martial arts skills is the same as saying that playing a football or basketball video game allows people to absorb the skills of those sports. No amount of video gaming will allow a person to throw a perfect endzone spiral, or swish a three-pointer past a 7-foot center. No amount of video gaming will allow you to get past a 300 lb. fullback, or to counter a bodycheck while handling a puck, or to execute a jacknife off a highboard. Only in the physical doing are such skills refined.
And lastly, NOTHING prepares you for the reality of injury. The shock of pain, even the minor pain of a misplaced blow, is enough to engage natural reactions that are to the detriment. The brain, my friend, freezes for a moment. That moment is all an aggressive opponent needs to finish you off. No amount of vid games can train you out of a natural human physiological reaction. Only the physicality of real-world experience can do that.
Don’t get me wrong, I love video games, they are loads of fun. But I cannot in good conscience endorse the idea that they are a martial arts training aid. To do so is to fool a group of eager people who could be good martial artists into believing a lie.
