Multiplayer Online Games (MOGs) are a thriving market leading to a multiplicity of game related internet applications. Enabling information exchange between games and these applications is essential, but still an unsolved challenge. Our Virtual Context Based Service (VCBS) middleware enables such an information exchange. The VCBS middleware is an interface between games and other internet applications, which also supports community activities. In this paper we describe the architecture of the VCBS middleware and its components, and introduce our concept for generic MOG interfaces.
