So, some time ago, I joined the Lost Media Wiki. I haven't really done much there other than tidy up some articles and make some comments, although perhaps I could get in on something at some point. One thing I've thought a bit about is whether or not there are any FOSS games that have become lost over time. I'm aware that there are certain aspects that might make it more likely for a FOSS game to stay preserved, such as the freedom of copying granted to users. Since proprietary games lack the freedoms given by FOSS, they seem to have more of a tendency to get lost. For instance, numerous articles on the Lost Media Wiki talk about missing Flash games. Some of these games may end up in a place such as the Internet Archive, but due to their proprietary nature there could be a risk of them being taken down (even if the owners of the game seem to have altogether abandoned it otherwise.) FOSS typically presents less risk of a takedown unless the terms of the FOSS license have been violated in some way or if there's a case of "free software but non-free media". Overall, FOSS games have less chance of getting lost because of the freedoms they give, while proprietary games restrict themselves at their own peril.
It is also worth noting, however, that the Lost Media Wiki also tends to talk about unreleased things, such as unreleased game builds and production material. It's likely that there could have been some proposed FOSS games or versions of FOSS games that have never seen the light of day and are only known to the public due to some announcements, promotions, or mere mentions/references. Perhaps this could be an area worth researching by enthusiasts of lost media and/or FOSS.
So, any thoughts?
