Spike was founded in December 1989 as Mizuki Ltd. (有限会社みずき, Yūgen-gaisha Mizuki). Its name was changed to Mizuki Co., Ltd. (株式会社みずき, Kabushiki-gaisha Mizuki) on October 18, 1991 and then to Spike Co., Ltd. in April 1997. Spike sold its book publishing business to Aspect in March 1999, and Spike was acquired by Sammy in April. Spike established a game development subsidiary named Vaill (ヴァイル株式会社) which consisted of former Human staff in November 1999, and it was eventually absorbed back into Spike in July 2001. In 2005, Spike was bought by Dwango. In 2012, it merged with its sister company Chunsoft and became Spike Chunsoft. Two games were in development at the time of the merger: Conception: Ore no Kodomo o Undekure! and Danganronpa 2: Goodbye Despair.
If you are browsing PlayPile to understand the history of Japanese game studios, Spike offers a case study in volume and genre specialization. Founded in 1989 as Mizuki Ltd., the company changed its name to Spike in 1997 before eventually merging into Spike Chunsoft in 2012. Their catalog on PlayPile contains 59 titles, with 41 published and 34 developed. The data shows a clear shift in output over time. They released only one game in the 1980s and four in the 1990s. Production exploded in the 2000s with 44 games, then slowed to 10 titles in the 2010s before operations ceased as an independent entity. Spike focused heavily on specific genres rather than a wide variety. Sports and fighting games dominate their portfolio, accounting for 16 and 15 releases respectively. They also made 11 adventure games, eight simulators, and seven hack and slash or beat em up titles. Their platform strategy was tied closely to Sony hardware. The PlayStation 2 holds the most games with 18 titles, followed by the Nintendo DS with 14 and the PlayStation Portable with nine. They released very few games for PC, with only one entry on Microsoft Windows in their entire history. The quality of their work varies significantly across this large catalog. Based on 17 rated titles, the average IGDB score sits at 67.5 out of 100. The breakdown shows thirteen good scores between 60 and 79, one great score above 80, and three mixed reviews in the 40 to 59 range. There are no poor ratings below 40. Their highest rated game is Nine Hours, Nine Persons, Nine Doors from 2009 with a score of 86.4. Other well-regarded titles include Dragon Ball Z: Budokai Tenkaichi 2 at 76.4 and MadWorld at 74.8. However, some recent releases performed poorly. Homefront received a 71.5 in 2011, while Dragon Ball Z: Ultimate Tenkaichi dropped to 48 in the same year. Spike operated as a publisher and developer for over two decades before merging with Chunsoft. They acquired Sammy in 1999 and later became part of Dwango in 2005. The final years saw the release of Conception and Fire Pro Wrestling in 2012, just before the company ceased to exist under its original name.
