After nine years of development, The Dark Mod is now a standalone game. Thief fans can now enjoy over 60 fan made missions which capture the essence of the Thief 1 / 2 games. Originally created as a reaction to Thief 3; with the upcoming release of Thief 4, many are comparing what was done here (a faithful extension of the old gameplay) to what Eidos has shown thus far. Can a little Doom 3 mod compete against a blockbuster AAA title? Should we even compare them?"All code in the The Dark Mod is GPLv3+, and the art assets are all CC BY-NC-SA 3.0 Unported which means it, unfortunately,cannot be distributed by even Debian. Still, an impressive feat!
