I really love the Thief series too, you taffers. I'm cautiously optimistic about this release. Even if it's been numbed down to cater for a wider audience, I think that the thief community themselves will tweak the game into something that works for them! I mean look at what happened to TDS, the community released some really cool patches that improved the texture quality, changed the look-and-feel to match that of Thief 2 more closely, even tweaked the AI to be more of a challenge.
I'd be happy with the game if they manage to achieve the same atmosphere as T1/T2, make it possible to 'ghost' through the entire game and have challenging stages to play.
This avid Thief fan, just cant wait!
