Nothing affects a person's life more than the games he played in his childhood. Games open a wonderful world of colors, light, secrets, materials, and relationships. The feeling of the game carries with us even into adulthood, and our desire to play remains in the subconscious and regularly emerges. In the colossal change of the world caused by computers, it remains unchanged, but its modification appearscomputer games [1]. In recent years, they have incredibly influenced children and adults.The development of computer technology and its impact on our lives are striking. Entertainment, especially computer games, is no exception in this sense. Playing computer (including electronic) games is a substantial percentage of this area. Of course, the development of these games is closely related to this. The development of computer games requires in-depth knowledge in the field of computer science, starting with programming, software engineering, or computer graphics (in some cases, in this sense, also virtual reality), through databases, artificial intelligence, and ending with, for example, the physics of games [2]. In short, as computer games become more complex, sophisticated, and immersive, the role of computer science in game development becomes increasingly important.In the secondary view, computer science is integral to every phase of computer game development. First, it provides computer game developers with the necessary tools to create, optimize and debug computer games, develop their game mechanics and gameplay, design interactive environments and characters, and create visual and sound effects [3]. Secondly, there is a close connection with the business aspect of computer games, including game marketing, distribution, or advertising [4].Following that, from the view of current game systems, it is necessary to address several areas (Figure 1). This applies mainly to the following areas (in no order of importance): graphics, sound, game logic and design, user interface (depending on the type of game also 3D interface, including player motion tracking or, e.g., his gesture sensing), sometimes different kinds of simulations or training modes, including the possible use of digital twins technology (if there is a game session with a potential real world), possible in-game physics, dynamics processing including scripting, the most immersive gaming experience possible, single-user or multi-user game mode including a possible cooperative mode, educational or research potential of the game or possibly data processing, artificial intelligence, and of course the economic aspect.
