It’s odd, considering Wikipedia and websites like GameFAQS seem to have the whole “huge list of games” thing already, but it’s refreshing to see a community come together and add to this growing list.
A Pastebin user named Data_Baser is attempting to compile an alphabetically organised list of every game released, including browser-based and mobile games alongside PC and console games. With help from a collection of 4chan users, the list is currently at 40,000+.
You can check out the full list here and maybe, just maybe, one of your childhood favourites has already been added. If not, add that to the ever-growing list and help the cause! My favourite game of all-time, Sonic the Hedgehog 2 for the Sega Megadrive, is in there all the way down at line 35,102.
