An online game is a video game played over some form of computer network, using a personal computer, video game console or handheld game console. This network is usually the internet or equivalent technology, but games have always used whatever technology was current: modems before the Internet, and hard wired terminals before modems. The design of online games can range from simple text-based environments to the incorporation of complex graphics and virtual worlds. The existence of online components within a game can range from being minor features, such as an online leaderboard, to being part of core gameplay, such as directly playing against other players. Many online games create their own online communities, while other games, especially social games, integrate the players’ existing real-life communities.
