Now, the petition is quite questionable, because:
1) As what have been said in another topic, Nintendo isn't affected by the fans' petitions.
2) Flappy Bird in SSB for 3DS/WiiU would be the biggest video-gaming joke ever. And the game is "dead" now, so, this bird doesn't even stand a chance !
3) For the petitions, again, it's the fans' desires. Nothing we can do about it. But about Fils-Aime, I think the cause is the way he shows games at the E3, who can, like @
naagza said, easily be turned into a meme.
