Because this topic falls primarily under education, psychology, and sociology subject areas, the vast majority of papers you'll write on it will require citation in the APA format. Citation can be confusing, and sometimes requires a little creativity when using unusual sources, but there are many guides that can help!
For the vast majority of citations, Purdue OWL's APA Formatting and Style Guide (7th Edition) is an incredibly helpful resource! For citing board games, video games, and other gamified media, the Lehigh University Libraries has published a handy APA Citation Guide for Games & Objects.
