This document summarizes research from the Alexander von Humboldt Institute for Internet and Society on the relationship between copying and producing in the video game industry. Through analysis of industry handbooks and interviews with 25+ game developers, the research finds that remixing game principles and graphical elements is generally accepted in the industry as a routine practice. Cloning games is also not seen as a major problem and is considered "part of the business". Copyright law does not strongly influence daily development practices. However, developers employ different strategies, with indies preferring low IP regimes and larger studios drawing from TV formats.
