As we leap into 2020, we have many things to celebrate. The year 2019 brought us our 50 th issue of Simulation & Gaming (S&G). As stated on our website: For more than five decades, S&G has served as a leading forum for the exploration and development of simulation/gaming methodologies used in education, training, consultation, and research. As we reflect back on those 50 years, we remain grateful for the leaders who inspired a generation of scholarship, along with those who continue their vision. I could easily fill volumes if I were to write about the many people who have contributed so much to the literature, but in this editorial I will mention just a few pioneers who I feel influenced our journal at key points in the 50 year timespan. James S. Coleman was one of the most (if not the most) pioneering and influential researchers in the area of social theory and socioeconomic factors in education and learning, although I sense that he is less known by many researchers in the simulation community today. Many editors and authors, including early S&G Editor-in-Chief, Cathy Greenblat were influenced by Coleman's work. A must-read article, not a part of the S&G collection, but a part of the rich Sage journals history would be a piece from 1968 titled, Academic games and learning (Coleman, 1968). Coleman suggested ".. .the use of games constitutes a fundamental change in the process by which learning takes place (p. 72) and is "designed to mirror the motives and interests of a real person in such as a situation" (p. 70). Coleman defined many of the concepts that authors would attempt to unknowingly (re)define in the literature many years later. As an editor, I continually witness a new breed of authors, writing about the principles of game design, attributing credit to recent authors, perhaps unaware of the original sources of some of these concepts. We need to know about Coleman's work and ideas because they are a part of the history of simulation and gaming. Greenblat compiled an important bibliography in Simulation & Games in 1972 titled, Gaming and Simulation in the social sciences. This bibliography included "items relevant to the use, evaluation, and design of simulations and games for the social sciences at the college and university level" (Greenblat, 1972, p. 477). It is of no surprise that Coleman's contributions are listed most often in this bibliography. Coleman applied games and simulation to social theory to address real-life circumstances.
