You're claiming I can't possibly know certain things while at the same time stating opinions (As facts no less) as if you somehow know better.
Claiming that the companies in smash have "owed up to their actions" is completely opinionated, is arguably untrue, not to mention that it is something you'd "Have to work at Nintendo" to factually know.
No duh, any third party addition is a special "situation". But what garners a special situation in Sakurai's eyes? We don't know all of his criteria. Take just about any Indie character people ask for, who are the best example of "Just any third party character". They're dwarfed in popularity by smaller third party characters like Rayman, Bomberman, Banjo and Kazooie, etc., and by extension are near worthless in comparison to the third party juggernauts in the game right now. But people still support them because we don't know if Sakurai could consider an Indie character as a "special situation". There's absolutely nothing pointing to that being the case, but the possibility is still open, if slim.
And I'm just basing what I've seen off of logical observations. Some companies have done stupid things in their past, but they don't hold it against each other because they are COMPANIES. Not people. They're main function is to make a profit. Grudges aren't profitable. Simple as that, they'd have to be led by unbelievably naive people to think otherwise.
