Over recent decades, we have built up an understanding of what constitutes good design and a positive user experience when interacting with software. This knowledge of humans, psychology, and interactions have been used to create engaging, intuitive software of all kinds. However, in recent years, this knowledge has increasingly been used for manipulative and subversive purposes. Understanding human expectations and cognition affords interfaces and systems to be designed to trick uers into performing actions that are beneficial to the creators, but not to the end user. Such design practices have been employed extensively in web design and more recently in video games. This project will involve investigating dark patterns and manipulative design practices employed in video games, analysing trends, and proposing classifications, as well as potential solutions to combat the rise of manipulative design.
