Yeah, it sucks if you're the entertainer. I recall getting the Wii around launch and the subsequent controller shortage. On launch day I found a place that had plenty and decided only to get one additional pair of Wii remote/nunchuck instead of three extra pairs. Kicked myself later when I was asked to go back and grab some more for the upcoming family gathering at Thanksgiving and discovered that of course the Wii accessory shelves were a ghost town nation-wide.
But thankfully all anyone really wanted to do was play Wii Sports which for the most part is a pass the controller game or for the most part just needs two Wii controllers. Where I get all

at Nintendo is boxing and tennis which clearly lose a lot of their potential for not having a second set of controllers in the box. I, a gamer, was at least smart enough to get one pair at the store earlier.
I miss the SNES/NES days of having two full controllers coming with the system. I just think that new casual users that you'd think Nintendo would try to do even more to coddle wouldn't immediately grasp the concept that multiplayer requires you to buy additional controllers. I can only imagine all the clueless parents after coming home from the launch or on Christmas morning that discovered that they'd have to go back to the stores in order to enjoy half the potential of the included game and finding that their trip was a waste of gas for the racks were empty and the employees merely shrugged when asked the question of when more much wanted goods would arrive. Really, one extra set honestly would not have killed Nintendo and would have given them bonus points to defining the system's focus and saving many a headache for their customers.
Jam it back in, in the dark.
