History
Timeline Ltd. was an American tabletop game company whose known publishing history falls primarily in the first half of the 1980s. The company operated during a formative period for role-playing games, when publishers were developing original rules systems, fictional settings, adventures, and supplements for dedicated hobby communities. Its best-known publication was The Morrow Project, a role-playing game released in 1980. The title established the core of Timeline Ltd.'s catalog and was followed by a succession of related or comparable publications. The company published more than a dozen supplements and adventures, indicating an effort to support role-playing campaigns with additional scenarios and playable material rather than relying solely on standalone rulebooks. Among the documented releases were Operation Lucifer, published in 1982, and The Starnaman Incident, published in 1984. These titles illustrate the company's use of adventure-oriented products to extend its role-playing offerings. Timeline Ltd. also published Time & Time Again in 1984, a time-travel role-playing game that represented a separate game concept from The Morrow Project. The new game was supported by at least one identified supplement, Holy Warriors, released in 1985. The known chronology suggests that Timeline Ltd. maintained an active publishing program from 1980 through at least 1985. However, the available reference material does not provide details about its management, financial structure, distribution arrangements, ownership, office location, or subsequent activity. It also does not establish whether the company formally ceased operations, was acquired, or simply stopped publishing under the Timeline Ltd. name. For that reason, the company's current status cannot be confirmed. Timeline Ltd. is therefore best understood as a historically documented specialist publisher in the early tabletop role-playing game industry. Its catalog included original role-playing games as well as a substantial number of supplements and adventures, with The Morrow Project serving as its central and most recognizable line.
