: The authors declare no relevant conflicts. For transparency, however, they wish to disclose that SB is the project manager of the Restart program, which was involved in generating the data. The Restart program is funded from the Finnish gambling monopoly company Veikkaus revenues through the Funding Centre for Social Welfare and Health Organisations (STEA) that operates under the Ministry of Social Affairs and Health. These funds did not support the present study. More than a decade ago, VMK was one of the co-founders and developers of the IGDB website, which is an open online database for various types of game knowledge. VMK never received salaries for that work, but when the website was turned into a company, he became a co-shareholder until a merger (2019) and has not been involved since. LL is researching a game-based digital intervention for depression at Aalto University.
