A play-by-mail game is a game played through postal mail, email or other digital media. Correspondence chess and Go were among the first PBM games. Diplomacy has been played by mail since 1963, introducing a multi-player aspect to PBM games. Flying Buffalo Inc. pioneered the first commercially available PBM game in 1970. A small number of PBM companies followed in the 1970s, with an explosion of hundreds of startup PBM companies in the 1980s at the peak of PBM gaming popularity, many of them small hobby companies—more than 90 percent of which eventually folded. A number of independent PBM magazines also started in the 1980s, including The Nuts & Bolts of PBM, Gaming Universal, Paper Mayhem and Flagship. These magazines eventually went out of print, replaced in the 21st century by the online PBM journal Suspense and Decision.
Starweb is a closed-end, space-based, play-by-mail (PBM) game. First published by Flying Buffalo Inc. in 1976, it was the company's second PBM game after Nuclear Destruction, the game that started the PBM industry in 1970. Players today can choose a postal mail or email format. Fifteen players per game assume one of six available roles and explore and conquer planets within a universe comprising 225 worlds. The object of the game is to attain a predetermined number of points which are generated by various actions during gameplay. Multiple game variants are available. Starweb is still available for play as of 2021 through the company Rick Loomis PBM Games.
Legends is a turn-based, role-playing game with a medieval setting. It is currently published in English by Harlequin Games. Jim Landes—owner of Midnight Games, the game's first publisher—began developing the game in 1984, eventually publishing it in December 1989 as a play-by-mail (PBM) game after over a year of playtesting. The initial game comprised a module and game system built on the publisher's existing game, Epic, and was run briefly as Swords of Pelarn before publication as Legends. The first of multiple game modules was Crown of Avalon, which allowed up to 200 players per game. Demand by 1991 was "incredible" according to Bruce R. Daniel in White Wolf. Games could be lengthy, initially between three and ten years of play, settling into an average of three years by 2002.
Alamaze is a computer-moderated, fantasy, turn-based game. It was published in 1986 by Pegasus Productions as a play-by-mail game. Reality Simulations later took over game moderation. The game itself has been played with multiple versions. The initial design, released in 1986, was replaced by the "Second Cycle" in 1991, offering changes to the kingdoms and game's history. The 3rd Cycle—"The Choosing"—emerged in 2015, doubling the available kingdoms while providing modifications to them. The publisher made additional changes to the player–game interface by 2017. In February 2019, Alamaze.co published the 4th Cycle, the world of Maelstrom, after two years of development. The game is currently run by Alamaze.co as a closed-end, play-by-email (PBEM) game in a turn-based format.
