Since I cba to read through the first 8 pages of this thread, I'm probably not the first to say this, but...
Anyone else see many similarities between the apparent ethos of Thief (according to Yahtzee at any rate) and that of <url=http://www.escapistmagazine.com/content/games/yahtzee/artoftheft>Art of Theft? Hiding in shadows, being encouraged to only attack guards if it becomes necessary, the less-than-social protagonist, the fact that exploration slightly off the beaten track is somewhat rewarded (e.g. AoT sometimes has loot in less-than-obvious places).
Such as getting the file on The Company from the C shelf in the records room (on the 7th heist). In fact, from about 2:56 to 3:12 he could easily be talking about Trilby (and guards) in AoT. AoT levels aren't what I'd call 'sprawling', though ; )
I do occasionally tire of the stream of ZP reviews about new games, so it's nice to see Yahtzee getting another chance to review an older one.
