I second this. You are better off enjoying the games while they are around, instead of constantly worrying about how long they will last. I own around 140 laserdiscs, and while some of them suffer laser rot, most of them are still fine, and I enjoy them while they aren't affected. Same with my PlayStation I got as a kid, I still play with it all the time, and while I will be sad at it's death, but I will remember all the great times I had playing with it. I also collect VHS tapes, and while some of them have lasted a great long time (some of my oldest are around thirty years old and are ex-rentals, but still have great image), while some are only fifteen years old and look old and faded. It depends on who manufactured the product and how well it was made.
