Possibly the most well-known FM outside of the Thief community, it definitely shows its age in some regards (especially the story, some elements feel a bit too "fan-ficy") and is a bit long in the tooth for repeat playthroughs. Still, this is a fan mission that is still worthy of your time and expands on groundworks laid out in Thief 2.

What lets it down in my opinion is there are a few missions that are just rather tedious instead of fun (Into the Fray, for example. Triggering every NPC into combat is just not fun, especially if you're going for a ghost run.)

The Grand Hotel, Down Among Dead Men, Of Ill repute and Shadowing the Enemy absolutely still hold up though, and are excellent missions in their own right.

Overall rating: 8/10, A *very* good fanmade expansion that feels right at home being played after Thief 2's OM's

I should also note that I used the Necro Age add-on "Shadows of the Necro Age" for my most recent playthrough, which I would also recommend trying out if you prefer higher quality textures.
