Problem: Extract the answer to the question from the following context. Question: Which games had more colors of plastic? Context: Japanese (Famicom) cartridges are shaped slightly differently. While the NES used a 72-pin interface, the Famicom system used a 60-pin design. Unlike NES games, official Famicom cartridges were produced in many colors of plastic.
