Challenge Magazine

[StainlessSteelCynic]

If you were searching Far Future Enterprises website, the Challenge magazines are not listed as separate items for purchase. Instead, the articles relevant to the game system are included as PDFs on the game CD-ROM.
So for example, if you bought the CD-ROM of 1st edition Twilight: 2000, you would also be getting all the Challenge articles that are for 1st edition Twilight on the CD.
