Computer Games?

A computer game is a piece of interactive software created with the primary purpose
of entertaining the user. This definition is not clear-cut but is still useful, since it characterizes the prototypical computer game. Seen from a programming viewpoint, a game typically is an interactive real-time simulation, possibly distributed. A model is maintained of a virtual world and this model
is updated and visualized in real-time according to the dynamics of the model and the interaction with the user or users. Computer game development is normally not viewed as constituting a computer
science field by itself. Computer game development is, however, an application of computer science that makes use of many different fields, including, but not limited to graphics, audio, HCI, operating systems, compiler design, algorithms, networks and distributed systems, software engineering, software design, and artificial intelligence.
