This thesis revolves around the long term experiences of in-app purchases (IAPs) in free to play mobile games and how they affect the overall player experiences as well as the satisfaction of the different IAPs on short as well as long term. In order to accommodate for this, the emphasis has been on both the overall experience of 3 different games, as well as the different form of IAPs purchases and their way of being applied within these games. This was in order to try and establish how different types of IAPs purchases might affect the experience differently, as well as whether or not different games were prone to vastly different evaluations of these purchases.
