Ron Barzso's 2003 offering is the Conquistadors & Aztecs Playset. The set features incredible foam temples and pyramids, Conquistador figures, Aztec figures, a vast array of accessories and character figures of Montezuma and Cortez. About the only thing missing is a virgin to be sacrificed. It all comes in a great litho box.
