The console itself was created by different partners and licensees, while 3DO received royalties on each console sold and on each game manufactured. They also offered a lower royalty rate than direct competitors Nintendo and SEGA. The console did not succeed, with a high introduction price and dubious game quality. The final nail in the coffin was when Sony entered the market with the PlayStation in 1995.

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.
