In this project we look into the virtual space in video games from their appearance till to date. Starting with the presentation of the first video game, we follow the evolution of virtual space from pixels to 3D visualization through characteristic games and the technological development of hardware and software.

 Then we see the relation between architecture and videogames according to the designing process of a virtual environment. Also the role that architecture has, to help the player figure out and overcome the challenges of a video game.

 We focus on the evolution of virtual space design in first-person shooter games, because of the special features that this category has in matters of visualization and relation between the player and the virtual environment. Our analysis is conducted through characteristic examples of maps of specific first-person shooter games that help us understand the designing process and its development.

 We mention the cinematic approach of single player video games and the relevance between the movies industry and the video games industry.

 We check over the interaction between the user and the virtual environment and its technological development. Physics in video games set the physical laws that stand in a virtual environment and we see how they contribute to a more realistic virtual space. Also we follow the technological evolution of visualization and controls in video games.

 In the last chapter we judge the course of virtual space and we express our opinion about the goals that the video game industry should focus. Finally we try to imagine what the future will reveal to us.
