A pen name refers to a creative name or nickname used instead of one's real name. Without revealing their actual identity, individuals can use this alias to play games or engage in creative activities. In other words, a pen name acts as a hidden identity known only to the person themselves.

The reasons why many people adopt pen names vary. In online creative activities, using a pen name when writing stories or articles allows for free expression while protecting privacy. In the gaming world, players can operate under a name that conceals their real identity and is recognized only within the game.

A pen name is not just a false name; it is also a means to create a new personality or activity domain through that name. It allows individuals to express different aspects of themselves and enjoy creative freedom, making it a very important tool for personal expression.
