Thief 4: Light Gem or No Light Gem? (Lifted from Community Chat)

What is so cumbersome about having it set on the mousewheel with everything else?

You just answered your own question.

Its basical fukcing science.

(would give more sense to this wall-hugging feature of TDS, too)

You're right, I totally forgot about that feature. Even when I was playing the game . I guess that if silhouetting was implemented in the same way that regular shadows are (i.e., guards are basically blind), then the difficulty increase wouldn't be too steep.
