Three-Sixty Pacific, Inc.

Three-Sixty Pacific was founded in late 1980's by avid wargamers and military history enthusiasts. Their games, although by no means selling like hot cakes, were always thoughtfully designed, with a high level of realism rarely seen in wargames, user-friendly mouse-driven interface, clean graphics, and excellent tutorial and on-line help files. While fellow wargaming houses such as QQP and SSI diversifies into non-historical and hypothetical wargames, Three-Sixty stuck to their first love: historical wargames, for all in-house efforts. After some diversification efforts in the late 80's - early 90's when the company published several action games, Three-Sixty developed and published Harpoon - a masterpiece based on Larry Bond's tabletop wargame that was inducted into Computer Gaming 150 Best Games of All Time and is still regarded today as THE best naval simulation ever produced. Despite the considerable commercial success of Harpoon and Atomic Games' V for Victory Series, complete failure of lavishly-produced but esoteric Theatre of War and lack of funds brought the company to its knees in early 1994.

U.S. Gold was a British computer and video game publisher and developer from the early 1980s through the mid-1990s, producing numerous titles on a variety of 8-bit, 16-bit and 32-bit platforms. U.S. Gold was founded in Birmingham in 1984 by Geoff Brown as the publishing division of Centresoft. The publisher continued to expand their operation well into the 1990s. However, a number of their licensing deals, particularly one with LucasArts, fell through, threatening to affect their income. In order to help consolidate their finances, they joined forces with UK software distributor CentreSoft to form the CentreGold Plc Group. Internal game development studios owned by U.S. Gold were the internally formed Silicon Dreams and acquired Core Design. The group was acquired by Eidos Interactive in April 1996. Eidos sold off CentreSoft and maintained Core Design as a developer but decided to discontinue the U.S. Gold brand. Silicon Dreams was sold back to U.S. Gold founder Geoff Brown and became the keystone for his new development venture Geoff Brown Holdings (GBH). The last retail game to bear the U.S. Gold logo was Olympic Games: Atlanta 1996, released in June 1996.
