The subject of „Business modeling in the video game industry during COVID-19 crisis on selected examples“ master's thesis is an investigation of the correlation between market share and business model of video game companies in the Republic of Croatia during the COVID-19 pandemic. The research part of the thesis is based on two in-depth interviews with each of the owners of three video game companies. The interviews were conducted over the period of July through October 2022. The companies in question are: Pine Studio, Exordium Games, and Red Martyr Entertainment. The data gathered via the in-depth interviews with each of the company owners were analysed over the period of 2019. through 2021. An investigation into the data has shown that Pine Studio introduced numerous changes into their business model in order to increase the competitiveness of their company, as well as the necessary adjustments (remote work) needed to continue working during the COVID-19 pandemic. Exordium Games continued working with publishers and introduced remote work as the answer to the COVID-19 pandemic. Red Martyr Entertainment did not introduce remote work, but did form a partnership with a publisher in 2021. Pine Studio was the most successful, with 11% market share in the Croatian video game industry in 2022.. Exordium Games stagnated in terms of income and expenditure from 2019. and into 2022. Red Martyr Entertainment experienced a rapid growth of total income in 2021., and an equally rapid decline of total income in 2022.
