Open world
There is no consensus on what the earliest open world game is, due to differing definitions of how large or open a world needs to be. Ars Technica traces the concept back to the free-roaming exploration of 1976 text adventure game "Colossal Cave Adventure", which inspired the free-roaming exploration of "Adventure" (1980), but notes that it wasn't until 1984 that what "we now know as open-world gaming" took on a "definite shape" with 1984 space simulator "Elite", considered a pioneer of the open world; Gamasutra argues that its open-ended sandbox style is rooted in flight simulators, such as SubLOGIC's "Flight Simulator" (1979/1980), noting most flight sims "offer a 'free flight' mode that allows players to simply pilot the aircraft and explore the virtual world". Others trace the concept back to 1981 CRPG "", which had a free-roaming overworld map inspired by tabletop RPG "Dungeons & Dragons". The overworld maps of the first five "Ultima" games, released up to 1988, lacked a single, unified scale, with towns and other places represented as icons; this style was adopted by the first three "Dragon Quest" games, released from 1986 to 1988 in Japan.
Tomato Adventure
After AlphaDream developed and released their first video game title, "", Nintendo wanted AlphaDream's permission to develop an entirely new role-playing video game with them, titled . They got the name from an idea of a game structure that utilizes gimmicky, toy-like controls that make it an RPG with action elements. It was finished and almost ready to be released for the Game Boy Color in Japan, until Nintendo released the Game Boy Advance to make the Game Boy Color obsolete. After noticing that, Nintendo requested AlphaDream to redevelop and rename Gimmick Land as "Tomato Adventure" for the Game Boy Advance. Nintendo also requested AlphaDream to add some easily recognizable characters in which reflects the new title, so that the game would have a more marketable image. Those were Nintendo's largest requests. Other changes are the quality of the graphics and audio being enhanced. Only two screenshots of Gimmick Land were released to the public by the developers. On the release date of "Tomato Adventure", Nintendo and AlphaDream announced a contest where twenty winners won themselves 1 kg of sweet tomatoes from the Kochi Virtue Valley area. The contest ended on February 28, 2002. The reason "Tomato Adventure" hasn't been released in the west is because the targeted age group was considered too low. Problems with the battle system and the game not being received well at the time of release were other factors as well.
