Ebbene sì, è in realizzazione una conversione per Doom3 a dir poco favolosa, ovvero "The Dark Mod", che, come il nome indica, si rifà ai mitici lavori creati col Dark Engine, ovvero il motore che ha mosso i primi 2 capitoli della serie Thief
Ma bando alle ciance, ecco il link al sito

Se vi siete sentiti delusi da Thief DS (io personalmente per nulla, anzi, ma c'è sempre qualche nostalgico ultra-ortodosso che non l'ha digerito

) questo potrebbe fare al caso vostro!
THE DARK MOD is a total conversion for Doom 3, turning it into a dark and moody stealth game inspired by the Thief series by Looking Glass Studios. We have a talented development team of about 15 regulars, including concept artists, modelers, texture artists and programmers. Our plan is to completely revamp the gameplay, AI, graphics, HUD and weapon set to fit our best view of a gothic steampunk universe as conceived by fans of the Thief genre. Our project has two main stages: first, to release a complete series of tools allowing fans to make their own stealth missions, and second, to create a unique campaign using those tools.
Install TDM on Windows
*Create a darkmod folder in your Doom 3 directory, like this: C:\Games\Doom3\darkmod
*Download the TDM Updater (see below for alternate download locations).
*Extract the tdm_update.exe from the downloaded ZIP and copy it into your C:\Games\Doom3\darkmod directory.
*Start the tdm_update.exe. The installer will connect to one of our download mirrors and start the download process.
*Be patient and wait. The download weighs 1.4 GB and will probably take a while.
*After installation, you'll find an executable tdmlauncher.exe in your darkmod folder, i.e. C:\Games\Doom3\darkmod\tdmlauncher.exe. Use this to start The Dark Mod.
