Extracted from the Wikipedia article Play-by-mail game.
Play-by-mail games (which became known as turn-based games in the digital age) have a number of advantages and disadvantages compared to other kinds of gaming. PBM games have wide ranges for turn lengths. Some games allow turnaround times of a day or less—even hourly. Other games structure multiple days or weeks for players to consider moves or turns and players never run out of opponents to face. If desired, some PBM games can be played for years. Additionally, the complexity of PBM games can be far beyond that allowed by a board game in an afternoon, and pit players against live opponents in these conditions—a challenge some players enjoy. PBM games allow the number of opponents or teams in the dozens—with some previous examples over a thousand players. PBM games also allow gamers to interact with others globally. Games with low turn costs compare well with expensive board or video games. Drawbacks include the price for some PBM games with high setup and/or turn costs, and the lack of the ability for face-to-face roleplaying. Additionally, for some players, certain games can be overly complex, and delays in turn processing can be a negative.
