This is a great idea! I am used to various fantasy-themed equipment and spell cards, but its about time a publisher did it for modern gaming! I am sure fans of Pangenre would also like to see other cards, such as modern armor and modern melee weapons as well (And don't forget about future items too!).
The cards are easy to interpret and read and the art is in black and white, but clear and attractive. All the info a player or GM needs is there!
