I like how someone came up with a genius idea to charge money for a game that lets people do the exact same thing they do when they listen to a cd.
"Here Bob, lets make a dance game"
"But Fred, people already dance in their living rooms won't it just be a waste of time. It will never sell"
"Ahhh Bob, how you misunderstand those easily parted with their cash. I promise you now, we stick some songs on a disk with some dance moves any sane person wouldn't attempt without several pints of alcohol and a bottle of whiskey for fear of looking foolish, and we're laughing all the way to the bank"
"I don't believe you Fred, but lets do it anyway, we've got a spare hour in our lunch break it won't take longer than that".
A bit later.
"Told you Bob, now how about we make another while we have 10 minutes?"
"Surely people won't fall for it twice Fred"
Some time later.
"Well Bob, my wife needs a new pair of breasts, how about we make a third"
"Honestly Fred, no one is gullible enough to fall for it a 3rd time"
