I actually brought it up with a few people.  Both concurrently agree with me that the drop of the Player Choice line sucks.   For those who don't know what the player choice is, when a game on a Nintendo platform sells over 1 million copies, the game becomes repackaged and sold as "player's choice", at a discounted price.  Usually the price drop will be around $19.99.  It was mainly used as a deterrence against buying used games.
 
Keep in mind that Nintendo is trading the "Player Choice" concept out for the "evergreen" belief to keep games on store shelves longer.
There is some truth to that.  In contrast to Sony and Microsoft, it is fairly hard to look for old titles made in 2006 and 2007 unless it is a player's choice title.

Also, it is not impossible to find these old games, however, it is very hard to find Xbox360 games made in 2005 and 2006.

I am too, but Nintendo is lowering their prices. NPC Pikmin and Big Brain Academy, for example, are now $20, and Metroid Prime 3 is technically at a lower price when included with Metroid Prime Trilogy.
 
But I do miss the official Player's Choice titles.

It doesn't bother me too much.  If I REALLY want a game, I can find it online for a good price in good condition.  Plus I know the location of at least 7 Gamestops and 2 independent retailers around me where I'll have a good chance of finding what I want.
 
Plus I never cared for the super ugly box art... that was always a huge beef with me.  I LOVE box art.

Nintendo of Japan actually does have Player's Choice for the Wii, but it goes by it's Japan name of "Best Price".
 
RE4 Wii Edition is one of them:
 

I miss the players choice too -- though Nintendo titles usually always sell well .. so I doubt we'll see any price drops for those anytime soon.

They just seem to have permanent lower shelf prices in Australia and I am fine with that, as it has the same effect.
