OK Thief games are just great, but I would like to empahsize how great GOG versions are: I have old copies of Thief 1/2 on DVD but it is difficult to use them. One problem is that the binaries are not compatible with multi-core processor (there is a workaround, but it requires some OS knowledge). But GOG versions work fine without any troubles: it is just amazing. I even play on 27'' screen with a 16/9 format image while I was expecting a 4/3 image. Definitively a great job from GOG.
