Gamer
Historically, the term "gamer" usually referred to someone who played role-playing games and wargames. Since they became very popular, the term has included players of video games. While the term nominally includes those who do not necessarily consider themselves to be gamers, it is commonly used to identify those who spend much of their leisure time playing or learning about games. There are many gamer communities around the world.

Online game
An online game is a video game played over some form of computer network or on a video game console such as the Xbox 360 and Playstation 3. This almost always means the Internet or equivalent technology, but games have always used whatever technology was current: modems before the Internet, and hard wired terminals before modems.
