Oh, don't get me wrong. ASCII is a great company and their games and controllers have been consistently great over the years.
I just laugh a little because back in 1988 (or was it 1989?) Nintendo took Camerica to court over the Freedom Stick because it very closely copied the design of their NES Advantage stick. In actuality, it was more like ASCII's Advantage. Anyway, such is life with regards to intellectual property I guess.
