Master of Monsters is a turn-based strategy game developed by SystemSoft for the MSX and NEC PC8801. It was ported to a variety of consoles and PCs including the PC Engine CD, NEC PC9801, and Sega Genesis/Mega Drive. While it never had the same success as its SystemSoft stablemate Daisenryaku, the game garnered a loyal following. Its success in the North American market on the Sega Genesis proved sufficient for a sequel on the Sega Saturn, and an anime art-style enhanced Sony PlayStation version titled Disciples of Gaia with a Japanese role-playing game feel. Master of Monsters: Disciples of Gaia was released in 1998.[1]
Gameplay engages players by permitting them to summon and move monsters around a board in an effort to capture towers and to eventually defeat the opponents (which are controlled either by other humans or by the computer program). Moves are based on a hexagonal board structure, such that every tile on the board is adjacent to six other tiles. Other notable features were the large variety of monsters, upgrading ("leveling up") of veteran units and control of a "Master" character who, if killed, can end the game for that player.
The focus of the game is strategic, despite the fantasy-type characters that might imply an RPG element. Other than the existence of the Master character and magic in the game, the gameplay is very similar to System Soft's more hardcore modern warfare strategic wargame series Daisenryaku, with the exception that some versions of the Master of Monsters (such as Master of Monsters – Final) series allow equippable items, weapons and armor.
The later Lords of Chaos by Julian Gollop of Mythos Games shares many of the same elements of summoning and tactics, along with the earlier title Chaos from 1985. David White, creator of the open-source turn-based strategy game The Battle for Wesnoth, cited Master of Monsters as an inspiration.[2] Master of Monsters was also compared to later games such as the role-playing video game series Pokémon (which also revolves around commanding monsters) and the real-time strategy game StarCraft.[3]
System Soft Alpha returned the game to its strategy-based roots, and the two entries in the Master of Monsters series as originally popularized on the NEC 9801 PC were updated by System Soft Alpha with new graphics and gameplay features. Two more sequels were made for Japanese Windows. Released on Japanese language Windows-based systems, the remakes include マスターオブモンスターズIII Special Edition, マスターオブモンスターズ4 ~光と闇の争覇~, Master of Monsters Value Edition (the original game, updated and with expansion packs added in), and 真・マスターオブモンスターズ Final. A spin-off of the game targeted towards the younger audience was titled Masumon Kids. A mobile version of the game was released in Japan.[4]
Edits and submissions to the site (including screenshots, box art, developer information, game summaries, and more) go through a verification process of fact-checking by volunteer "approvers".[2] This lengthy approval process after submission can range from minutes to days or months.[3] The most commonly used sources are the video game's website, packaging, and credit screens. There is a published standard for game information and copy-editing.[4] A ranking system allows users to earn points for contributing accurate information.[5]
Registered users can rate and review games. Users can create private or public "have" and "want" lists, which can generate a list of games available for trade with other registered users. The site contains an integrated forum. Each listed game can have its own sub-forum.

MobyGames was founded on March 1, 1999, by Jim Leonard and Brian Hirt, and joined by David Berk 18 months later, the three of which had been friends since high school.[6][7] Leonard had the idea of sharing information about computer games with a larger audience. The database began with information about games for IBM PC compatibles, relying on the founders' personal collections. Eventually, the site was opened up to allow general users to contribute information.[5] In a 2003 interview, Berk emphasized MobyGames' dedication to taking video games more seriously than broader society and to preserving games for their important cultural influence.[5]
In mid-2010, MobyGames was purchased by GameFly for an undisclosed amount.[8] This was announced to the community post factum , and the site's interface was given an unpopular redesign.[7] A few major contributors left, refusing to do volunteer work for a commercial website.{{Citation needed|date=June 2025} On December 18, 2013, MobyGames was acquired by Jeremiah Freyholtz, owner of Blue Flame Labs (a San Francisco-based game and web development company) and VGBoxArt (a site for fan-made video game box art).[9] Blue Flame Labs reverted MobyGames' interface to its pre-overhaul look and feel,[10] and for the next eight years, the site was run by Freyholtz and Independent Games Festival organizer Simon Carless.[7]
On November 24, 2021, Atari SA announced a potential deal with Blue Flame Labs to purchase MobyGames for $1.5 million.[11] The purchase was completed on 8 March 2022, with Freyholtz remaining as general manager.[12][13][14] Over the next year, the financial boost given by Atari led to a rework of the site being built from scratch with a new backend codebase, as well as updates improving the mobile and desktop user interface.[1] This was accomplished by investing in full-time development of the site instead of its previously part-time development.[15]
In 2024, MobyGames began offering a paid "Pro" membership option for the site to generate additional revenue.[16] Previously, the site had generated income exclusively through banner ads and (from March 2014 onward) a small number of patrons via the Patreon website.[17]
