Ōzumō: Heisei Hero Basho, a crossover for the Famicom featuring "super-deformed" interpretations of Gundam, Ultraman, and Kamen Rider. It is often credited as the first video game to cross over characters from other forms of media. Heisei Hero Basho was developed by Banpresto staff as a congratulatory gift to Sugiura shortly after assuming role of company president. Beginning April 1990, the company supplied video arcades with prizes for UFO catchers and merchandiser machines, such as those designed after Ultraman and Kamen Rider characters. Over 70 million were sold in the year 1990 and contributed to Banpresto's 30 million capital increase. In April 1991, Banpresto introduced Super Robot Wars, a tactical role-playing game for the Game Boy. Developed by external studio WinkySoft, it was a spiritual successor to its Compati Hero series of games, crossing over popular mecha licenses like Getter Robo and Mazinger-Z. Super Robot Wars was a commercial success, attributed to its release during the popularity of mecha anime in the early half of the decade. It became one of the company's most-successful games, spawning a multi-million-selling franchise with several sequels, remakes, and other forms of media. Super Robot Wars is considered important and influential for the genre, and contributed to the early success of the SD Gundam media franchise. As of 2016, the Super Robot Wars series has sold over 16 million games across all available platforms. Banpresto also began producing children's rides, using the likenesses of characters such as Anpanman, Super Mario, and Thomas the Tank Engine. By 1992, Banpresto was worth 1.4 billion yen. The company began expanding its operations as a result, starting with the establishment of Sanotawa, a sales and distribution network subsidiary, in February. Banpresto found additional success in arcades with the release of Ugougo Luga, a stuffed toy that sold over 2.6 million by the end of the year. The company continued to develop and publish video games for home consoles. Among its most successful releases was Super Puyo Puyo, a Super Famicom conversion of Compile's Puyo Puyo series that sold over one million copies. In February 1994, Banpresto established Banpre Kikaku, Ltd. in Kita, Osaka, which became its primary video game development division. As Banpresto was largely a publisher of games by other studios, the move allowed it to experiment with original game concepts and handle development of video games in-house. In addition, Banpre Kikaku also served as a second office,
