CD's have burn holes in them, that goes threw layers, and layers. The best way to keep your CD games in check is, to keep them in their cases, and not out too long.
I am getting tired of all of this anti-cd and bit-rot nonsense. These are only specs based off production, made to scare the consumer into buying into downloadable content. TAPE is a far better storage material, and long lasting as somebody said in a documentary. We should still be using tape for our Videos, and even videogames as well. Even records are long lasting. They say the same crap about books. I have books from 1940's that I read still, without breaking apart.
Reality check is that most materials made today are crap compared to materials used before. I have been copying CD's for a very long time, and I have noticed ( like coins ) the cds have become very smaller, thiner, and easier to bend.
All of these things they mentions is from mishandling by consumers, and harsh conditions. The entire western society is heavy influenced because of the religious ideas. Like how our weekends surrounds the sabbath, or the idea of new.
My old boss from the first job I got by myself said it best. Maintain, maintain, maintain. By that he means if you take care of something it will
last a real long time. That is all anybody has to do with anything. So stop worrying.
Just worry about how future generations are going to be sports playing arseholes who spends their free time trying to slove the worlds problems, working on vehicals, and flying machines. The least amount of entertainment they will have is teather and crap Wii virtual.
If it wasn't for the whale eating Nipponese, being creative. that is how the entire world would have been like. Stuck in the atari generation forever.
Another thing to think about his how all of the early products ( even during the 1980's ) was made to last, and be used for a very very long time. There are transforming chairs from the 1800's that still works the same as they did when they were new. Swords and guns that are constantly kept in shape, passed down from generation of warhawk, to generation of enthusiast.
So stop worrying. If you are so worried then write to the makers of the games to make a second release, for the system. For collecting purposes.
