Requirements in Conflict: Player vs. Designer vs. Cheater

There are significant interactions between video game stakeholder emotional requirements and security require- ments. Counter-intuitively, some traditional security requirements are not necessarily met by the game implementation some forms of security breaches are condoned by the stakeholders (if not actually demanded by them) and the requirements engineering process must support these contradictions. We present an overview of security requirements for video games and show how stakeholder diversity introduces significant complexities to the requirements negotiation process. Our analysis of certain security threats, and their emotional motivations, shows that these motivations form an important element of the emotional requirements and that significant context is necessary for properly capturing the emotional requirements related to security. Finally, we show how emotional requirements can be used to guide security goal development for this domain and pro- pose the use of in-game justice systems to allow players to address security violations in realtime.
