Free on GOG.com, no DRM, and packaged to run on Windows. Worlds of Ultima: The Savage Empire - GOG.com Ultima Worlds of Adventure 2: Martian Dreams - GOG.com These are actually very expensive to buy on ebay. You may think you can get Savage Empire for pretty cheap, but it's actually some EA 10-game CD pack and it doesn't have some of the stuff with it. Yes, they aren't the normal Ultimas, but they are Ultimas and they are free. And Ultima IV is still free if you haven't picked it up.
