Clay started Capstone Games in August 2015 as an avenue to make hard to find heavy games widely available throughout the world. The first project, Arkwright, was a complete success and sold out within 4 months. Since then, Clay has been focusing Capstone on medium to heavy euro titles, printing them for retail release. Some notable games include Lignum, Three Kingdoms Redux, Wildcatters, and the Coal Trilogy. In 2017, Clay created the Simply Complex brand as a new line of games that feature lots of wooden components, low rules overhead, and complex strategies while playing in under one hour. The Climbers and The Estates were the first titles in this line. Race for the Chinese Zodiac is now the third title and is from the designers of Three Kingdoms Redux!
