an open world game. The game is the first to use a fog of war effect in its catacombs, which obscures most of the playing area except for the player's immediate surroundings. The game has been voted the best Atari 2600 game in numerous polls, and has been noted as a significant step in the advancement of home video games. GamePro ranked it as the 28th most important video game of all time in 2007. In 2010, 1UP.com listed it as one of the most important games ever made in its "The Essential 50" feature. Entertainment Weekly named Adventure as one of the top 10 games for the Atari 2600. A sequel to Adventure was first announced in early 1982. The planned sequel eventually evolved into the Swordquest series of games. In 2005, a sequel written by Curt Vendel was released by Atari on the Atari Flashback 2 system. In 2007, AtariAge released a self-published sequel called Adventure II for the Atari 5200, which is heavily inspired by the original; its name is used with permission from Atari Interactive. Robinett himself took the idea of using items from Adventure into his next game, Rocky's Boots, but added the ability to combine them to form new items. In both the 2011 novel Ready Player One and its 2018 film version the Easter egg in Adventure is prominently mentioned as the inspiration for a contest to find an Easter egg hidden in the fictional virtual reality game OASIS, and finding the secret room within Adventure is a core plot element within both versions, with footage from the game (specifically the Easter egg) incorporated into the film version. The Lego Atari 2600 set includes three "cartridges" that open to reveal scenes inside them. The cartridge for Adventure has a scene of the game's castle with an egg hidden at its center, reference the Easter egg.
