A game is an activity that involves a group of players who engage in an abstract challenge, defined by rules, interactivity and feedback which results in a quantifiable outcome often eliciting an emotional reaction. The game can be anything from a competitive, skill based video game to a pure narrative experience powered by your imagination. Games can be played with physical objects such as chess pawns or marbles, board games, card games or even your mobile phone or computer.

The formal definition of a game includes aspects such as mechanics, objectives and rules that form part of the ludological agreement. However, it is also important to consider other elements of a game such as the context and how it is perceived by different people.

Some people play games for the excitement of winning. Others do not play to win, but rather because they enjoy the social aspect of the game and the opportunity to interact with other people. Many people play games to escape their world and find an activity that does not involve real-world tasks such as cleaning the house or going to work.

For example, some people find refuge in role-playing or fantasy games and can feel free to express their personalities without fear of judgement. This can be a very positive activity for those who are abused, oppressed or simply bored with their real-world environment.

Other people find a sense of accomplishment when they make progress as a player in a game. This can be especially true for those who are able to master complex challenges within a game that requires a high level of skills and strategic thinking. For some, the gratification of making progress in a game can be as satisfying as accomplishing a goal at work or school.

The context in which a game is played and the purpose of playing it can greatly influence its nature. For example, a game that is played in a competitive or adversarial context can be seen as being a harmful activity that leads to negative emotions and other consequences such as depression. On the other hand, a game that is used as an educational tool can be seen as having positive effects such as improved concentration or social skills.

The emergence of digital technologies and new forms of gaming have created new challenges for the development and classification of games. For example, digital games often have complex game mechanics that require a large amount of computational power to run and provide feedback on the actions of the player. In addition, these games often use audio to support the action and have the additional benefit of being able to include microphone and webcam inputs for in-game chatting and livestreaming. These factors have resulted in some critics calling for a new, more rigorous and formal definition of a game that takes into account the unique nature of digital technologies. Other game critics such as Katie Salen and Eric Zimmerman have argued that the definition of a game should be flexible enough to allow for new types of games that may not fit into traditional categories.
