An online game is a game that is partially or exclusively played through a type of computer network, most commonly the Internet. Its range extends from a basic text-based game like World of Warcraft and Multiplayer Online Role-Playing Games (MMORPG) to virtual worlds that are populated by many players at the same time. Modern video game consoles as well mobile phones and computers all come with this feature. Online gaming is a revenue source in addition to the traditional sales of video games, games software, and portable systems.
In contrast to video games, which have a set end time the online games can go on indefinitely. They often also involve the interaction of players who can be located anywhere in the world and transactions – typically points or game enhancements but sometimes real money – are carried out in virtual environments.
Online games can be free or paid-for. They can be played through a Web browser or through an app that is independent and can include many features like chat, forums and communities. Many of these games are designed towards young children and many come with social features that allow them interact with other players.
Some experts suggest that online games can be addictive and cause sleep or appetite issues, as well as concentration issues. Some experts believe that playing too much can be a sign of mental health problems, and should be treated by an expert medical professional. However, the vast majority of gamers are responsible and many parents use video games to teach children about the importance of school, work and healthy lifestyles.
