The user interacts with a computer or with other players by entering artificial game characters with a mouse, keyboard or gamepad and usually receives screen reactions. The player thereby controls a virtual character as a representative by a predefined world. He can move in the given world, depending on the game, to varying degrees freely. The game developer has previously defined rules and goals. These rules must be observed by the player in order to achieve the goal. A mark of quality for computer games is often the freedom to act.
Single Player mode
Computer games are played mainly in the single player mode. The game situation is influenced only by the players themselves and the computer. The actions and reactions of the opponent, often called bots, are calculated by the computer. The level of artificial intelligence of non-player characters is often a quality criterion in games with single player mode and with the development of computer technology, it progresses further and further away. Scores can be stored in the form of save games to resume them later or to send to others.
Multiplayer mode
Many computer games also support the multi-player mode where players can play against each other. They are played either on the same computer (with simultaneous play often with the help of split-screen technique or by alternating hot-seat system) or via networked devices: via the Internet or a local network (to a greater extent on LAN parties where many like-minded people connect their computers together). The multiplayer mode allows for a direct comparison of game skills and allows performance measurement. Examples of such e-sports games are: Quake III Arena, Unreal Tournament, Warcraft 3 and Counter-Strike.
Online games with a high number of players (MMO or MMORPG)
On the Internet, it is possible for many players to participate in a computer game. Here, the actual game is computed on a server and each user can participate from a networked computer. The most important form of online games are the Massively Multiplayer Online Role-Playing Game, MMORPG, where thousands of players are playing a role playing game.
