GOG.com now offers the first couple of Worlds of Ultima games gratis on their DRM-free marketplace, saying the free editions of the Ultima spin-offs are being provided courtesy them and Electronic Arts. The games are Worlds of Ultima: The Savage Empire and Ultima: Worlds of Adventure 2: Martian Dreams, and here's word on the sub-series: "Lord British presents two adventures you would never think are possible in Ultima universe. Players of the Ultima series may recall that the black moonstone the Avatar found at the start of Ultima 6 can be used to teleport you anyplace and anytime. That is why ORIGIN Systems have, using the Ultima 6 engine, sent the gamers worldwide on two unexpected journeys in both space and time."
