I'm having a total brain fart, but not too long ago, I came across a site that had listings for old games that have been released to the public and are now free. This site had games like Dune 2, Relentless, some of the King's Quest series, as well as other classic Sierra games.
They used a term for these games, and I can't remember it for the life of me. Something like "openware"... it was "<something>ware", I know that much. Anyone know what I'm talking about?
edit:
Abandonware!! that's what it is
First hit on google for "abandonware":
