Distributed Virtual Environments (DVEs) are a large class of real-time simulation systems. We present an implementation-independent methodology for measuring, analyzing, and comparing DVE systems performance. The methodology comprises of a process of requirements elicitation and their conversion into measurable objectives. The process for determining quality requirements for a DVE is discussed, with a focus on interaction-based scenario analysis. An example is given with a simple game - Asteroids - that has been modified to support two players (users).
