PC games are played on a computer using devices like a keyboard, mouse, joystick or gamepad with speakers or headphones. They differ from arcade, video, and console games which are often connected to televisions. Games that were originally only in arcades have evolved into PC games played at home without inserting cash. Computer game development is typically done by small enterprises that hire various staff like programmers and artists to create games. To play computer games on a local area network requires two or more PCs, a router, and network cables connecting the machines with each PC needing a network card and copy of the game.
