  This paper introduces time-based addiction, which refers to excessive
engagement in an activity that results in negative outcomes due to the
misallocation of time. This type of addiction is often seen in media-related
activities such as video games, social media, and television watching.
Behavioural design in video games plays a significant role in enabling
time-based addiction. Games are designed to be engaging and enjoyable, with
features such as rewards, leveling up, and social competition, which is all
intended to keep players coming back for more. This article reviews the
behavioural design used in video games, and media more broadly, to increase the
addictive nature of these experiences. By doing so the article aims to
recognise time-based addiction as a problem that in large part stems from
irresponsible design practices.
