[转]Game Engines

http://content.gpwiki.org/index.php/Game_Engines

A game engine is the core library functions used in a game, usually related to graphics, input, sound, networking and other systems.

Engines are separate from game-specific code, which enables different games to use the same engine. (Games of different genres even, in some cases.)

Engines have different features. When picking an engine, you have to pay attention to whether or not it satisfies the needs of your game.
