Maps of Mastery poster maps and terrain cards are designed on a subtle but noticeable 1-inch grid for use with most miniatures games and tabletop RPGs. Many of them feature fine colored terrain lines to help players distinguish at a glance between walls (red) and pits (orange), objects that provide cover (green) and objects that impede movement (yellow). Doors have light blue rectangular markings, while locked or sealed hatches have the same rectangles but in the same red color as the walls.
Product cover images are also color-coded: A blue background means the product was designed primarily for science fiction gaming. Orange suggests a Fantasy theme. Green indicates that the product should be equally at home in a sci-fi, fantasy, or even modern setting. As products with a very modern, urban theme appear in the store, their covers will share a gray background.
