These questions come off as a little misleading to me. Well, more than a little.
Segata Sanshiro: Not a marketing technique.
Working Designs: Didn't exactly pave the way for special editions. Nor did they have a patent to them.(Which means they had exclusive rights granted to them by the government to create special editions, which I suppose shouldn't count as it wasn't in the question..)
What video game character was inspired by a missing piece of pie?: I think this question is just intentionally misleading, calling pizza "pie", if the answer is pac-man, is kind of rare overall. >.> I mean yeah some people do just call it a pie, but if you go into a pie shop and order pepperoni, you're gonna get some odd looks..
