The decision of which business model to follow, when developing a game, has become one of the most important choices a company has to make. In our re- search we have compared and evaluated different kinds of freemium based busi- ness models. The objective with the research is to follow a constructed business model when developing a game. The game concept is based on an existing game called GoSupernova complemented with a litarature-based study. Which parts of the concept that has been implemented follow the client’s requests, but also discussions on which parts are most essential for the gameplay. The goal with the game concept is to have good potential to consolidate a continuous playing behaviour. To accomplish this we had to take many different factors into account that could affect the user’s opinion of the game, both in short and long term. The game should be satisfying enough to get users to play, but unsatisfying enough so users to have something to work for. This can also benefit in-app purchases, when users try to achive different goals.
