Doom fans petition Raven for GPL Hexen source

sfraggle writes: "Doomworld is reporting about a group of Doom enthusiasts petitioning Raven to GPL the source code to Heretic and Hexen. Although the source code was released several years ago, the license is so restrictive as to be next to useless. Now over 30 programmers working with projects derived from the Doom source have drafted an open letter to Raven in the hopes of getting the source finally re-released under the GPL. The letter is backed by a petition signed by over 300 people."
