Entertainment Software Publishing, Inc. [lower-alpha 1] (ESP) was a Japanese video game publisher headquartered in Shibuya, Tokyo. It was founded in 1997 as a publisher for games developed by the Game Developers Network (GD-NET). GD-NET, which included companies such as Treasure and Game Arts, was established due to concerns over smaller developers not having the same financial backing like larger game companies did, as production of console games was beginning to rise. ESP was best known for publishing shoot 'em ups and role-playing games. While primarily a publisher, ESP also developed a handful of games internally.

Contents

ESP primarily published games for the Sega Saturn and Dreamcast. When both systems met their demise, the company started shifting operations towards consoles such as the PlayStation 2, PlayStation Portable, and Nintendo DS. ESP was purchased by Game Arts in 2002 and became its publishing division. In 2004, ESP was sold to D3 Publisher, which had noticed ESP's track record and lineup of well-received titles. ESP was merged with D3 Publisher and its parent company, D3 Inc., in 2010.

Many games that were published by ESP, including Grandia , Radiant Silvergun , and the Bangai-O series, have received praise from critics. Several have sold well and have been ranked among the best in their genres. In the past, ESP helped co-publish several Japanese massively multiplayer online video games, and also collaborated with other game companies on various projects.

History

ESP was established to publish games by smaller developers for consoles such as the Sega Saturn (pictured above). Sega-Saturn-JP-Mk2-Console-Set.jpg
ESP was established to publish games by smaller developers for consoles such as the Sega Saturn (pictured above).

In the late 1990s in Japan, several Japanese video game developers, including Treasure, Quintet, Sting Entertainment, and Game Arts, joined forces and established Game Developers Network (GD-NET). The purpose of GD-NET was to establish mutual assistance with one another. [1] As the video game market in Japan began growing in size, the costs for developers to produce games for consoles was also rising. [1] Members of GD-NET did not have the same financial backing like larger companies did, and believed that creating healthy relationships between them would increase their chances of surviving the industry landscape of the time. [2] Companies under the network proposed a plan that would allow them to focus their resources on game development instead of production and promotion of their titles. [1] [3]

GD-NET members established Entertainment Software Publishing (ESP) in November 1997. [4] Youichi Miyaji, the president and CEO of Game Arts, was appointed president of the company. [5] ESP was funded by many game studios, including Japan Art Media, CSK Research Institute, and Onion Soft, as well as most of the companies that were part of GD-NET. [6] [7] Additional funding was provided by CSK Holdings, the parent company of Sega. [8] [3] GD-NET members would create and produce games, while ESP would handle marketing, sales, and promotion of these games. [4] [5] GD-NET members believed that ESP would allow them to gain more recognition within the industry, as companies such as Sega, Nintendo, and Sony Computer Entertainment would have taken credit for their works when they were published. [4]

One of ESP's first hits was Grandia for the PlayStation and Sega Saturn. [9] Developed by Game Arts, Grandia was released in 1997 [10] to critical acclaim. [11] Treasure's Saturn conversion of the arcade game Radiant Silvergun was also released to acclaim for its gameplay and mechanics, [12] and is cited among the best and most influential shoot'em up games created. [13] [14] [15] Slayers Royal and its follow-up Slayers Royal 2 , both based on the Slayers light novel and anime series, were also commercially successful. [16]

In 1998, Sega discontinued production of the Sega Saturn in Europe and North America amidst poor sales. [17] While the Saturn was still being sold in Japan, Sega largely abandoned the system in favor of the Dreamcast, which it released the same year. [18] As such, ESP began to shift its publishing operations from Saturn to Dreamcast and other consoles like the Nintendo 64. It published Bangai-O for the latter console in 1999, which while critically successful was produced in limited quantities out of concern over its niche appeal. [19] [20] ESP commonly participated in the Tokyo Game Show and other major video game events in the country, where they regularly presented their more popular titles such as Silhouette Mirage . [21] ESP also began publishing games for the PlayStation 2, which had become the best-selling video game console in Japan and outsold the Dreamcast by a wide margin. [22] [23] [24]

In 2002, ESP was acquired by Game Arts and became the latter's publishing division. [25] In 2004, ESP was purchased by D3 Publisher, a Japanese video game studio best known for its Simple series of budget games. [26] [27] D3 purchased 100% of ESP's stock for a total of 120 million yen. ESP's track record and lineup of commercially successful games was the reason for the acquisition. [27] In addition to publishing other developer's titles for systems like the PlayStation 2 and Nintendo DS, ESP also began developing its own games such as Hajime no Ippo Portable Victorious Spirits for the PlayStation Portable. [28] ESP co-published several Japanese massively multiplayer online games as well. [29] It announced at the 2005 Tokyo Game Show it would also begin production of games for the PlayStation 3. [30] In 2008, the company partnered with Treasure, the only remaining GD-NET company to still have working relations with them, to form a publishing project known as "Treasure × ESP". [31] The project lead to ESP publishing Bangai-O Spirits for the DS, a critically successful sequel to Bangai-O. [32]

On 1 April 2010, ESP and D3 Publisher were merged into the latter's parent holding company, D3 Inc., wherein both ESP and D3 Publisher were dissolved, while D3 Inc. was renamed D3 Publisher. [25] [33] The year prior, D3 Inc. had been majority-acquired by Namco Bandai Games. [34] [35] [36]

<i>Radiant Silvergun</i> 1998 shooter video game

Radiant Silvergun is a shoot 'em up video game developed and published by Treasure. It was originally released in Japanese arcades in 1998 and subsequently ported to the Sega Saturn later that year. The story follows a team of fighter pilots in the far future who are battling waves of enemies summoned by a mysterious crystal dug up from the Earth. The player hosts an arsenal of six different types of shots to choose from, and a sword to destroy nearby targets. The stages are tightly designed to present players with scenarios that can be approached differently with the various weapon types.

<i>Bangai-O</i> 1999 video game

Bangai-O is a multidirectional shooter developed by Treasure and released in 1999 on the Nintendo 64 in Japan. It was ported to the Dreamcast worldwide shortly after with some gameplay changes and updated graphics and audio.

<span class="mw-page-title-main">Treasure (company)</span> Japanese video game developer

Treasure Co., Ltd. is a Japanese video game developer based in Tokyo known for its action, platform, and shoot 'em up games. The company was founded in 1992 by former Konami employees seeking to explore original game concepts and free themselves from Konami's reliance on sequels. Their first game, Gunstar Heroes (1993) on the Sega Genesis, was a critical success and established a creative and action-oriented design style that would continue to characterize their output. Treasure's philosophy in game development has always been to make games they enjoy, not necessarily those that have the greatest commercial viability.

Ikaruga is a shoot 'em up developed by Treasure. It is the spiritual sequel to Radiant Silvergun (1998) and was originally released in Japanese arcades in December 2001. The story follows a rebel pilot named Shinra as he battles an enemy nation using a specially designed fighter called the Ikaruga which can flip between two polarities, black and white. This polarity mechanism is the game's key feature and the foundation for its stage and enemy design. All enemies and bullets in the game are either black or white. Bullets which are the same color as the player are absorbed while the others will kill the player. The game features both single-player and cooperative modes.

The fifth generation era refers to computer and video games, video game consoles, and handheld gaming consoles dating from approximately October 4, 1993, to March 23, 2006.
