Nowadays, thriving and intensive use of computer technology is making more and more people spend their time in virtual reality. This paper focuses on virtual reality in computer games that enables simultaneous interaction of a large number of players from around the world. Virtual reality is being observed here as a potential evolution of a new communication media and its further development with the impact that this kind of communication has on the individual and culture. Computer game avatar is a digitally animated being that a player uses to interact with the virtual environment. Regardless of the fact that an avatar is in its essence a sequence of lines of programming code, we use here the term "being", because it is managed by – humans. This begs the question of whether the avatar actually is a form of a cybernetic organism that exists as a combination of our emotions, personalities, state of mind, attitudes and opinions and the programming code and technology. MMORPG (Massively Multiplayer Online Role Playing Game) is a stage where all the interactions in this new communication media are made. These are online games, which provide real-time connection of players from all over the world and enable them to play a variety of roles through their avatars. This paper provides an overview of the whole process of interaction that takes place in virtual realities of computer games: from the avatar creation process and methods of communication, the slang and vocabulary used by players, ways of compensating the lack of non-verbal communication in using technologies as a method of communication to the impact on the real lives of individuals. Since this topic is rarely represented in academic papers in Croatia, the processes described in this paper can contribute to future research.
