Recently we were talking about the upcoming Thief 4, which inevitably brought us back to the time-honored Thief series. On the thief-thecircle.com site there are tons of fan missions and mods, but I wanted to post a few links to some mods that nicely update the graphics of Thief 2.
First off, the widescreen mod. If you get no other mod try this one, it makes a noticeable difference when playing the game on big monitors.
Next, the texture enhancement pack. Nice texture updates!
Finally, the Doom 3 engine is being used to make a new set of fan mission tools, called the Dark Mod. You'll need Doom 3 to play it, not Thief 2. Here's a link to a standalone mission called The Tears of St Lucia. The AI needs some tweaking, but this conversion will be amazing if they get it right.
If anybody's having problems installing these, please post here too. I'm no techie but maybe we'll find a solution.
Update 10/17/09: The Dark Mod is out. Dust off that Doom 3 disc!
