Something of interest for stealth game fans: an unofficial patch which upgrades the Dark Engine (used by the Thief games and System Shock 2) has been released, making it capable of running smoothly on modern systems. Among other things, the patch enables widescreen support, 32-bit textures and OpenAL.
