In this thesis I analyse the reward systems of cooperative and competitive Multiplayer games – the games I have chosen were built for a Single-player campaign with Multiplayer as additional content. My main focus is on the Multiplayer and the reward systems of that game mode. The reward systems are important to consider when designing a game for fans of Multiplayer games, as a faulty reward system might hinder the aspect which makes Multiplayer games special – to be playing together and go for the same goals with other people whether it is of a competitive or cooperative nature.The games I research are as recent as they were first released in 2012. These games are Kid Icarus: Uprising and Resident Evil: Revelations – the latter receiving a port to the HD consoles in 2013. The games were primary made for a single-player experience and therefore may not be fully implemented to support social needs of a Multiplayer game.To do my research I have played and tested the reward systems of the games myself and analysed how they may influence player behaviour and what effects that may have on the Multiplayer experience.

This dissertation presents a study that explores the idea of implementing PCG in game bits. Procedural Content Generation (PCG) refers to content in games that is created by an algorithm rather than a human. Game bits is the part of game content that relates to graphics, audio and other elements that don’t directly affect gameplay. The goal was to find out what a PCG implementation in game bits needs to affect player behaviour. Qualitative play sessions with interviews were performed to examine potential ways this could occur. Results show that no noticeable behavioural differences appeared due to PCG in game bits, but three properties are set up detailing how implementations would increase the odds of affecting player behaviour. These properties are: PCG implementation changing visuals drastically, different visual elements matching and game space generation matching game bits repeatedly.
