My mind directly went to Laserdisc before I realized you were talking about the generic category 😅.
cd/dvd/blueray doesn’t become bad that fast, properly stored they can easely live to 50+ years (except the writeable variant). they are physically etched which helps with longevity.
VHS or other types of magnetic storage is more of a chore, they often don’t survive the passing of time.
When a new game is released I usually check if it’s steam deck compatible, if it isn’t for no specific reason (like, a 2d platformer, I’m not going to expect a high fidelity 3d game to work) I’m way less inclined to buy it. The market is there and really should be picked up.
