It's simply because in general, Nintendo's games are well known for being of the highest quality available. That's the primary reason for why their games retain their value so well.   

 

Edit: This article from nintendoworldreport also answers some questios as well. One reason being that a lot of Nintendo's games have a huge amount of replayability.   

Uncharted 2 is well known highest quality too. That doesn't stop Sony from selling it at 15 pounds price one year after release bringing great value for gamers.

The only reason why Nintendo games are still so expensive is Nintendo greed.
