You do realize that you are posting about a fantasy movie as if it was real?
I hope that you also realize that you can't learn martial arts by playing video games.
The Rwandan Genocide was real and not long ago.What was it 900,000 dead by machete? At the rate our leaders are pushing race and class wars and destroying our economy it won't be long until we're all fighting with swords and knives if we're lucky enough to have them.Ammo will run out for 99% of the population in weeks at best,then the old skills,the skills that can't be banned or confiscated will be as useful as they always were.
You're correct,fighting skills can't be learned playing video games alone.
However the military has learned the video game generation learns quickly and has good reflexes and eye hand coordination from video games.I play them myself at 43 and do believe they help train you to think quick.Thinking fast is one kind of speed needed in combat.The faster you register a threat the faster you can respond.Video games IMO can build that kind of speed.MPH hand and foot speed still needs good old hard work and proper technique.
Mental speed is why old Martial Art masters often can beat younger and faster men.
Reaction speed called sensitivity in Chinese Boxing can be improved well into old age.Strength,endurance and MPH hand and foot speed unfortunately can not.
Why learn to fight with a sword if you can't take it with you anywhere?
You can take a walking cane which is almost as effective if you have the right cane and can be used using sword techniques.
The Samurai Miyamoto Musashi beat several other Samurai in duels with a wooden boken and in his most famous fight he carved a large stick out of an oar.
IMO the ability to use everyday items effectively in a fight is a good skill to have.That said I have a safe full of modern weapons and ammunition and have the skills to use them at a high level.
