Q. Aren’t you asking companies to support games forever? Isn’t that unrealistic?
A: No, we are not asking that at all. We are in favor of publishers ending support for a game whenever they choose. What we are asking for is that they implement an end-of-life plan to modify or patch the game so that it can run on customer systems with no further support from the company being necessary. We agree that it is unrealistic to expect companies to support games indefinitely and do not advocate for that in any way.
