Sheets specifically designed for Castles & Crusades. Plenty of room for all your equipment, information and spells.
I like that they are a nice combination of both modern functionality (3.x era) and old-school sensibilities (AD&D). Diving the sheets up by what ability the characters need (Strength, Dexterity, Wisdom) is a nice call back to the old "golden rod" sheets of a bygone age.
Yes you can find sheets on the web for free, but these are worth the price.
