Game preservation is a hot topic right now, on the back of Sony's decision to end physical discs for new PlayStation games come 2028. It came up during a recent shareholders' meeting at Square Enix, where the company stated it has ways and means of keeping releases available to some extent, even if they aren't necessarily what fans would like.
A questioner raised how, although Square Enix is publishing a lot of remakes and such at the moment, much of the original software is unavailable on modern systems. Likewise, a number of live-service and phone-only games, which are often very difficult to preserve meaningfully without publisher help, have been shut down. The question finished by asking what the general policy is towards keeping media available.
