Overview
Nightfall Games is a British role-playing game publisher founded in Glasgow in April 1993 by Dave Allsop, Anne Boylan and Jared Earle. The company became associated primarily with SLA Industries, a science-fiction and dystopian role-playing game created by Allsop. Nightfall released the first edition of SLA Industries in September 1993 and followed it with supporting material, including the Karma sourcebook in 1994. The company also became known for publishing The Terminator RPG. Nightfall's early history included a change in ownership when Wizards of the Coast acquired the company after the publication of its first SLA Industries sourcebook. Allsop, Earle and Tim Dedopulos restarted Nightfall in 1998 after recovering the rights to SLA Industries from Wizards of the Coast. The revived company subsequently worked with Hogshead Publishing from 1999 to continue publishing SLA Industries. When Hogshead ceased operations in November 2002, Nightfall moved to a publishing relationship with Cubicle 7 Entertainment. Dave Allsop, the creator of SLA Industries, temporarily resigned from Nightfall in 2004. The company later returned to independent status in April 2011 while retaining Cubicle 7 as its publisher. In April 2012, Nightfall announced that Romark Entertainment had acquired film and television rights to SLA Industries and that a joint venture was intended to develop comics, games and other media. Publicly documented updates on that initiative reportedly ceased after March 2013. Nightfall Games was incorporated in the United Kingdom on 28 February 2018. The listed directors at incorporation were Dave Allsop, Jared Earle and Rapson. The company is principally identified with tabletop role-playing intellectual property rather than with electronic video games, despite its classification in a broader games and entertainment taxonomy. Its defining business role has been the creation, stewardship and licensing of SLA Industries and related role-playing products, together with selected licensed publishing projects.
History
Nightfall Games began in Glasgow, Scotland, in April 1993, founded by Dave Allsop, Anne Boylan and Jared Earle. Its first major release was SLA Industries, issued in September of the same year. Created by Allsop, SLA Industries established the company's identity as a publisher of dark, science-fiction-oriented tabletop role-playing games. A first supporting sourcebook, Karma, followed in 1994. After the release of Karma, Wizards of the Coast acquired Nightfall Games. The arrangement did not permanently end the original founders' involvement with SLA Industries. In 1998, Allsop, Earle and Tim Dedopulos restarted Nightfall after regaining the rights to the property from Wizards of the Coast. This relaunch returned SLA Industries to the center of the company's activities and restored Nightfall as an independent creative and publishing operation. In 1999, Nightfall formed a publishing partnership with Hogshead Publishing for continued SLA Industries releases. Hogshead ceased operations in November 2002, prompting Nightfall to establish a relationship with Cubicle 7 Entertainment. Cubicle 7 subsequently remained involved as publisher even after Nightfall announced in April 2011 that it had returned to independent status. The company also became associated with The Terminator RPG, extending its portfolio beyond its proprietary SLA Industries setting into licensed role-playing games. The available reference material does not provide a complete publication chronology for that title or identify all editions and publishing arrangements. A notable personnel change occurred in 2004, when Dave Allsop temporarily resigned from Nightfall. Allsop was the creator of SLA Industries and one of the company's founders. The reference material does not specify the duration or operational effects of his departure. Nightfall pursued broader exploitation of its intellectual property in the 2010s. In April 2012, it announced that Romark Entertainment had acquired film and television rights to SLA Industries. The parties also described a joint venture intended to produce comics, games and other media. No further updates on that initiative are recorded after March 2013 in the supplied reference material, so its final outcome is unclear. Nightfall Games was incorporated in the United Kingdom on 28 February 2018. The directors identified at incorporation were Dave Allsop, Jared Earle and Rapson. The company is therefore documented both as a long-running creative publisher founded in 1993 and as a UK-incorporated entity established in 2018. Its historical importance rests primarily on SLA Industries and its role in developing and licensing specialized tabletop role-playing properties.
