Computer game

in this week, we learned about computer game..

then, what is computer game..

A computer game is any sort of game that is played using a computer.

A computer game is not necessarily a video game, or vice versa; for instance a text-based role-playing game could be played verbally by a blind person, which is clearly no longer a "video" game, and the first generation of video games, such as Pong, used dedicated electronic circuitry not even remotely resembling a computer.

next points are Mods

Mos can refer to a number of things

Internet slang for moderators, people on an Internet discussion forum who can edit or otherwise change the state of other users' comments, similar to (though less powerful than) administrators.
A mod, short for modification, is an add-on to a computer game, usually (but not always) a first-person shooter.
Modifications made to a computer in order to improve its appearance.
A British youth subculture of the 1960s. See Mods (youth movement).
MODs, computer music files created with tracker software.

and in order to operate games, we need to many game engines(ex, graphic,physics,ai,etc..)

so..what is game engine?...

In computing, a game engine is the core software component of a computer game. It typically handles rendering and may handle additional tasks such as AI, collision detection between game objects, etc. The most common element that a game engine provides is graphics rendering facilities (2D or 3D).
The term arose in the mid-1990s, especially in connection with 3D games such as first-person shooters. Such was the popularity of id Software's Doom and Quake games that rather than work from scratch, other developers licensed the core portions of the software and designed their own graphics, characters, weapons and levels—the "game content" or "game assets."
Later games, such as Quake 3 and Epic's 1998 Unreal were designed with this approach in mind, with the engine and content developed separately. The licensing of such technology has proved to be a useful auxiliary revenue stream for some game developers. At the very least, reusable engines make developing game sequels much easier and faster, a valuable advantage in the competitive computer game industry.
The continued refinement of game engines has allowed a strong separation between rendering, scripting, artwork, and level design. It is now common (as of 2003), for example, for a typical game development team to be composed of artists and programmers in an 80/20 ratio.
A practical definition of a game engine is whatever most game developers would prefer not to write (as opposed to the things that make their game seminal, such as levels, artwork, textures, animation, sound tracks, etc.). The extreme realization of this idea has been for some game developers to take existing games and simply modify their art resources.
Game engine development is a popular project amongst computer science students, hobbyists, and game developers alike. It can require strong interdisciplanry understanding of geometry, color theory, and computing. Being largely visual, however, these developers consider it fun and rewarding. Crystal Space, for example, is a popular open source multiplatform game engine

what makes a good game , it is important thing

i think that popular gmae is a good game :)

hot and cool media

Telephone is a cool medium, or one of low definition, because the ear is given a meager amount of information. And speech is a cool medium of low definition, because so little is given and so much has to be filled in by the listener. On the other hand, hot media do not leave so much to be filled in or completed by the audience. Hot media are, therefore, low in participation, and cool media are high in participation or completion by the audience. Naturally, therefore, a hot medium ... has very different effects on the user from a cool medium...
