Using third party software to communicate with other players when it is not intended or prohibited by the game client is also considered extremely rude and unsportsmanlike.
In some games, players are generally encouraged to be polite and courteous to one another, and avoid excessive profanity and trash talk.
In progression-based games such as MMOs, players who take action in response to undesirable outcomes (vengeance) are often looked down upon and considered sore losers for not respecting their opponent's victory.
[6] "Rage-quitting", in which a player logs out if they find themselves in a losing situation is also frowned upon, particularly if doing puts their team at a disadvantage or prevents statistics from being updated.
[4][7] In games involving circumstances where many players need to meet at an agreed-upon time, such as in a raid in World of Warcraft, it is considered bad etiquette to show up late.
