About this font family
The Sideshadow family has 4 weights, Regular, Bold, Light and Half Light (which is intermediate between Regular and Light). The distinguishing feature of the font (you don't actually need me to explain this, do you?) is the partial shadow to the side of the main character, giving it a distinct and eye-grabbing look.
The zip files contain both OTF and TTF versions of the font - install one version only.
