Privateer was a DOS game made by Origin sometime in the 1990’s, when a 486 CPU with 8 MB RAM was still the top of the line ! I remember buying it and being flabbergasted by the video and renders in the game intro.
A group of people took the opensource vegastrike engine, and rewrote Privateer with up-to-date graphics.
Version 1.0 is out *NOW* and it’s playable for Windows, Linux and Mac OS X. The file weighs in at 178 MB, so you are advised to use a bittorent download if your internet pipe is not large enough (and it keeps their ISP happy).
