Online gaming has drastically increased the scope and size of video game culture. Online games have attracted players from a variety of ages, nationalities, and occupations. The online game content can also be studied in the scientific field, especially gamers' interactions within virtual societies in relation to the behavior and social phenomena of everyday life. As in other cultures, the community has developed a gamut of slang words or phrases that can be used for communication in or outside of games. Due to their growing online nature, modern video game slang overlaps heavily with internet slang, as well as leetspeak, with many words such "pwn" and "noob". Another term that was popularized by the video game community is the abbreviation "AFK," meaning "away from the keyboard," to refer to people who are not at the computer or paying attention. Other common abbreviations include "GL HF," which stands for "good luck, have fun," which is often said at the beginning of a match to show good sportsmanship. Likewise, at the end of a game, "GG" or "GG WP" may be said to congratulate the opponent, win or lose, on a "good game, well played". The culture of online gaming sometimes faces criticisms for an environment that can promote cyberbullying, violence, and xenophobia. Some are also concerned about gaming addiction or social stigma. However, it has been argued that, since the players of an online game are strangers to each other and have limited communication, the individual player's experience in an online game is not necessarily different from playing with artificial intelligence players.
