I bet they've done it more times than I can even count to without falling asleep counting.
What really boils my goat about Nintendo is, like all game companies, their tendency to put on airs and assume the credit for the creations which gave them popularity without respecting the idea that the creators had of what the creations ought to be like.
It is that disrespect for the primal nature of a creation that leads to all manner of vileness in the entertainment industry, and it is a well-trodden subject. I think people in the electronic game business tend to view things with rose-tinted glasses because of Nintendo, and while I know why the marketing strategy was chosen, I also know that it is a cover for the fact that Electronic Gaming has been largely possible due to the history of the Gaming business being somewhat...er...unorthodox in its methodology.
By "Gaming," I mean, profiting from a game that you share with the public...ahem.
