It's like those old Choose Your Own Adventure books... but in video! It's genius!
Pity your actors are so crappy, but that kind of gives it a naive charm. The idea
is awesome though.
Is this just a fun thing that you did for a con or something?
Or are you going to monetize it in some way?
I'm thinking the easiest way to do it would be to have large numbers of "fighters", and then simply link, in the video, to a purchase page for their weapons on something like
True Swords - Samurai Swords, Full Tang, Real Blades, Movie, Anime, Video Game, & Manga Replicas
