Why do Nintendo game prices never fall?

[binary solo]

For Nintendo profit per game sold>volume. And of course most of their games sell high volume as a ratio of install base anyway. Also not making sequels within a generation (usually) means each game is that sub-franchise's game for that console generation. Therefore you want Nintendo's game from X franchise for the Wii U / 3DS then your only option is to buy that one game and you have to pay alomost the same price as the day 1 buyers.

Not sure how that holds up for franchises like Pokemon that do have a few games per generation. But I think Pokemon fans are so used to getting screwed over (e.g. no multiple saves per game) that permanent full price for the game won't raise the ire of a subdued player base.

Also because 3rd parties have very little appeal among the Nintendo fanbase, with a few exceptions, even when a game is Nintendo exclusive, when a 3rd party drops the price it really does not pose any threat to Nintendo games. Therefore Nintendo has an effective monopoly on their own consoles, and when you have a monopoly you charge more. If Nintendo wasn't in hardware competition with Sony and MS, and now Smartphone and Tablets, Nintendo would probably be charging >$60 for games too.

Or the TLDR version: because they don't have to.
