The aim of this work is to answer, where the limits of virtual reality in game development lie and what level of immersion games can achieve. To this end, the following research question is asked: What are the current challenges of virtual reality and to what extent are fully immersive realities possible in VR games? To answer the research question, an experiment was carried out based on a literature search, which tested the test subjects‘ sense of immersion when playing a specially created application.         
The results of the work show that the limits of virtual reality in game development have their origins particularly in socio-cultural, but also technical aspects. Above all, the consequences of escaping reality through VR gaming are ethical challenges that game developers must deal with in the long term. From a technical point of view, conventional VR glasses are not enough to fully experience virtual reality. The greatest potential for increasing immersion when playing VR games lies primarily in the additional equipment, which is only being developed slowly due to the high level of research effort. In the future, fully immersive realities may well be possible thanks to technical breakthroughs in neuroscience.Further research in the field of VR gaming could relate to the socio-cultural consequences of increasing immersion or technical developments, in particular haptic suits, omnidirectional treadmills or neuroscience as a peripheral area of game development.
