Good Old Games, the popular place to get classic PC games that have been remastered to work on modern operating systems without horrific DRM is offering two great classic Origin titles for free. For a limited time you can download Worlds of Ultima: The Savage Empire and Ultima: Worlds of Adventure 2: Martian Dreams provided by GOG and EA free of charge. The Ultima Worlds series of games used the Ultima VI engine technology to create two unique RPG worlds: the dinosaur-filled lost land of Eodon, and the bizarre landscapes of Mars.
You can grab both games for free by visiting GOG.com. Obviously you will need to have a Good Old Games account to download and play these games. Ironically GOG didn't have to give these games away - people were begging for them to be added to the site so they could buy them.
