[quote name='Indigo_Streetlight']What we might see in the future is that certain titles will have more of tendency to fail due to differences in manufacturing techniques. Though if I can still come across CDs from the 80s in excellent playing condition, that's telling you that not everything is designed to instantly fall apart--likewise not all games are going to be exposed to the same conditions of sunlight and moisture.
Another thing we don't know about is advances in game restoration that might occur in the future. Would it be possible to "cook" the disc and reburn the game data in a manner similar to CD-RWs, only more sophisticated?[/QUOTE]
Both true. The writable material in the vast majority of CDs and DVDs is made of material which oxidizes over time if not properly sealed, so good quality disks are of the utmost importance. (Note to those who weren't aware: this is what therpgfanatic meant by "CD rot".) Quality of materials affects other storage mediums as well (paper, film, etc.), so of course it's to be expected with digital ones; I have books where the pages have yellowed quicker than others, due to things like the acid content in the paper.
Book restoration has been around for a lot longer, but I think a greater hurdle with data storage mediums is the invisibility, to the naked eye, of the content. Yet like you said, it's possible that there could be some future technology that will enable easier data restoration, much like how today's tech has improved book restoration.
For right now, there are some great archival-quality blank media available, but AFAIK, they generally aren't used for mass-produced games, and it's becoming harder all the time to legitimately archive games for personal use without running into legal and technological (read: copy protection) stumbling blocks. I feel it's simply a matter of time, though, especially if the market keeps trending towards downloads, much as music has. In the meantime, I'll just take good care of my stuff, but I've always done that anyway, so it shouldn't be too hard
