Part of the poor sales of N64 games can be owed to their obscenely high prices.

Part of the reason PS2 generation games sold in abnormally high volumes was because they were dirt cheap to manufacture and certain third parties (EA, Activision, and their like) routinely over-shipped, and that gen was the heyday for when games sold in bins like these:

 

It was also, perhaps, the first generation where people began buying lots of games and not playing as much as half of them (or was that just me? I know I can't be the only idiot that did that!).
