Unfortunately, not every downloadable game gets to stick around forever. This page offers a listing of all 366 extinct games on the site. These are games that were only released digitally and are no longer available to buy, download, or log into. There may be exceptions for some — availability in a single territory or a decades old CD-ROM edition — but for the broadest consumer market these games are unattainable.
Keep in mind, there are illicit means to play some of these titles but we will not link to or comment on torrents, cracks, or emulators.
