Realmz: "Abandoned Freeware" RPG
Well this is most peculiar case.
Realmz is indie Mac/Windows RPG from 1994, with official scenarios/expansions being released up to 2002.
It was developed by a guy called Tim Phillips and published through his company
Fantasoft.
(
He also published some games for other Mac Indie Developers, including the original Exile Trilogy by Jeff Vogel.)
In November 2008, Tim Phillips released the full version of Realmz (Mac & Windows) as a free download. Plus the registration numbers for the commercial scenarios/expansions made available to everyone on the Realmz Yahoo Group.
However, Fantasoft's website has since expired.
