Well, for a franchise that got popularity shot up it's ass after Brawl announced Olimar, this sure is a dying board.
Brawl is usually the game to be featured in when your video game character needs a little more recognization, but being featured in a Smash Bros. game is definitely not the high point of the game's popularity, or the major spike that sent it into motion. It almost never is.
And, to tell you the truth, this is more like it:
[Before Brawl] "Pikmin? Oh, you mean that one game? Yeah, I've heard of it/have it."
[When Olimar was announced] "Oh yeah, Pikmin! That's where Olimar is from, right?"
[When Brawl was released] "OMG OMG OMG OMG Can't wait for Pikmin 3!"
[A year or so after Brawl was released] "Pikmin... let me think... oh yeah! That Olimar dude from Brawl!"
