I object to that comment!
Tekken was one of the best fighting game series of all time and though many of the moves were visually impressive much of the timing and tactics of real fighting were transferable.
That other stuff you mentioned about Abernethy and Morris is spot on though. When I started looking into bunkai such resources didn't exist. I've come up with my own views on Bunkai, but by my estimation Abernethy and Morris are the only Karateka publicly doing anything worthwhile.
Regarding the historical stuff, all I can say is don't believe the hype. Shotokan was changed in a number of ways, but none of them are anything to do with the technical content or application of the art. Itosu and Funakoshi made alterations that made teaching to groups easier and much was not passed on for a variety of social cultural and historical reasons. But very very very few karateka can honestly say their ryu or line of teachers taught any different historically. Also most of what was supposed to have been changed is actually the oldest version on record. The other Shorin ryu styles are all founded by people junior to Funakoshi and represent more modern ideas and amalgamations of styles. While the Japanese changed the emphasis of Shotokan to sport from self defence, and consequently made alterations based on aesthetic, many of their technical changes are still an improvement on the unscientific chinese methods used in other ryu.
Karate kata were different from master to master and everyone was fine with this until karate went to Japan. The dumbing down idea is just snobbish nonesense with no true historical basis.
