Thief II plays it safe: if it ain't broke, don't fix it. In this case, it is a great decision by the developers.
Thief II begins right after the first game, Garrett is being persued by a corrupt town marshal and must find the answer to finish off a conspiracy that is threatening the future of existance. Yep, same supernatural thing here. But in this case the story works as a whole, and if you go out and play Thief III after this one, it'll all be one concise package.
New features include the addition of robe arrows: now you can climb roofs with the aid of this trinket. Garrett also has the aid of his new mechanical eye: he can se further and scout ahead traps and dangers.
The gameplay is the same even with the new features. Graphics-wise, the game looks a little bit sharper than the old one, but not so much, if you liked the old one, you'll feel right at home here. The sound effect quality manages to be even better this time around, so turn up your speakers for the ride.
Thief II is a great game worthy of its name. Unfortunately the developer closed its door sometime after the game came out, so Thief III was picked up by another studio. It is really worth playing all of the chapters and sequels, including fan made leves.
