Bigger challenge is games that die because the back-end servers are turned off and the assets are discarded. I'm on a team reverse engineering an old MMO from 2011. We've spent years rebuilding the server from packet captures and disassembly because everything official got nuked. This is just one of many examples where the customer "buys" a thing in their mind only later to find out they really didn't buy anything.

The legal situation is a mess too. We're not competing with anyone (game's been dead over a decade), we're not selling anything, but we still operate in this gray area wondering what's fair use versus what crosses a line. Copyright law wasn't written with "what if the company abandons it and erases it from existence" in mind.

Meanwhile every day that passes, more of these games just vanish permanently because preservation is treated as piracy.
