A gamer is a person who plays interactive games, especially video games, tabletop role-playing games, and skill-based card games, and who plays for usually long periods of time. Some gamers are competitive, meaning that they can compete in some games for money, such as Overwatch, Fortnite, League Of Legends, Counter Strike: Global Offensive, etc. In some countries, such as the UK and Australia, the term "gaming" can also refer to legalized gambling, which can take both traditional tabletop and digital forms. There are many different gamer communities around the world. Since the advent of the Internet, many communities take the form of Internet forums or YouTube or Twitch virtual communities, as well as in-person social clubs. Originally a hobby, it has evolved into a profession for some.
