Student,
If you know how to look there is very, very little of the surface of arts that isn't posted on the net. The full extent is unreal, great, good, bad and of course ugly.
I wasn't playing games, the kata video's are just the surface of the lake. Nobody really has answered how any system systematically approaches bunkai, it's much deeper than the few video's suggest (and sometimes much less depending), nor has anyone really tackled skill acquisition and skill resets required with aging, and the development of strategic and tactical thinking.
Fortunately my instructors never went the 'basics' and 'advanced basics' approach, they just kept working deeper and deeper and occasionally posted some of the upcoming signposts.
Until you've really worked on students who've kept working for 20+ years the depth of instruction is hard to describe.
Much of it is beyond experience of those who don't pay the price, long term training.
It really doesn't matter if others believe it exists, its enough that I practice what I preach and my students find it useful.
