text: Unified Patterns for Realtime Interactive Simulation in Games and Digital Storytelling.
  This paper discusses the state of the art in realtime interactive simulation patterns, which are essential in the development of game engines, digital storytelling, and many other graphical applications. We show how currently popular patterns have evolved from equivalent, or, at least, very similar concepts, and are deeply related. We show that game engines do not need to choose a particular pattern, but can easily combine all desired properties with little or no overhead.
