Nintendo seems to get a free pass for it. On a side note, I think many Nintendo fans have a hard time understanding why Sony only makes 2-5 games in any given series. "Sony kills off it's series too often. Why don't they make 157 sequels, prequels and spinoffs like Nintendo?" That's one of the main qualities that drives PS sales, is that PS fans generally like to get a constant feed of new IP, and not something like the 70th Crash Bandicoot game.
