Here's a [review](https://web.archive.org/web/20040000000000*/https://www.ocia.net/reviews/tradewars/tw2k2.shtml) of the TWGS. Here's a [link](https://web.archive.org/web/20040000000000*/https://www.ocia.net/reviews/tradewars/tw2k2.shtml) to two Trade Wars related projects, which even includes a downloadable [zip file](https://web.archive.org/web/20040000000000*/https://www.codefortress.com/code/tradewars.zip). Remember TW_ATS and it's maker, Badhouse Software? Lots of porn to be had at [Badhouse.com](https://web.archive.org/web/20040000000000*/https://www.badhouse.com/) these days.
What about [TWAR](https://web.archive.org/web/20040000000000*/https://webhome.idirect.com/~twar/). Kind of crooked that you can still order it, tho it hasn't been updated in SIX YEARS!
