Wasnt one of the last Thief games promising to be great, and then axed?
DUDE I LOVE the Thief games, and yeah, but the team got axed, they are spread all over now, though there were comments about in some way working together...
IMHO it was revolutionary, an FPS where the goal is really NOT to shoot anyone. in fact with no guns and only a slightly effective dagger it was also unique.
I actually just re-installed Thief III on my laptop a few weeks ago, found a widescreen patch, and am about 1/2 way through the game again
