At least, it keeps them at a way higher trade value than others.
Man, if you look at some stores, you can still find some First party Wii games (Like Kirby Return to Dreamland) at 50 bucks !!
There's also this image of quality of your purchase that Ninty tries to capture and maintain for a long time which makes your purchase even more justifiable by keeping the value of it's games pretty high.
