ClassicGaming.cc is a stylized resource for a small number of elite classic video games. Each one of their featured games gets an in-depth walkthrough and resource guide. Recently Wing Commander Privateer got a full treatment and a variety of information is now available. Everything from equipment details to commodity tips are up for eager new privateers. Some of the information can be obtained elsewhere, but this site does a good job of bringing it all together and organizing it for easy consumption. ClassicGaming has guides for both Privateer and Righteous Fire. I always liked reading different authors' mission suggestions, and our own Righteous Fire guide should be getting an update soon as well. ClassicGaming also features a pretty nav map of the Gemini Sector.
The map makes a common mistake with a jump line from Troy. Resident Stellar Cartographer Lesnick points out that the jump from Troy to Pollux should actually go from Troy to War. This shows up occasionally in various maps because of how the lines appear to overlap in the game, but there is no actual tunnel from Troy to Pollux. The Gemini and Exploratory Service Systems are also not marked. You can find a collection of various maps at the CIC here.
