Underdogs
Robert found the Underdogs site, which is a repository and encyclopedia of historic games. Underdogs finds computer games from as early as the 70s, games that have been released as freeware or otherwise released into the public domain, and preserves and promotes them.
From their About section: “Home of the Underdogs is a non-profit site dedicated to the preservation and promotion of underrated PC games (and a few non-PC games) of all ages: good games that deserve a second chance after dismal sales or critical reviews that we feel are unwarranted.”
Anyone remember M.U.L.E.? They have it.
Remember One Must Fall 2097? Yep, that too.
