A second manga series, illustrated by Kenji Mizuta, began serialization in Mag Garden's Monthly Comic Blade in December 2009.

An anime series adaptation by White Fox aired in Japan between April and September 2011, and has been licensed in North America by Funimation.

[1] Steins;Gate's gameplay requires little interaction from the player as most of the duration of the game is spent reading the text that appears on the screen, which represents either the dialogue between the various characters or the thoughts of the protagonist.

For these decision points, Steins;Gate presents the user with the "phone trigger" (フォーントリガー, fōn torigā) system.

[25] As Rintaro sends a text message about the incident to his friend, Hashida "Daru" Itaru, he experiences a strange phenomenon and the people around him disappear, with no one else noticing anything had changed.

As Rintaro reaches wit's end, he is approached by Amane Suzuha, a girl from a future ruled by SERN due to their possession of a time machine, who tells him that he needs to return to a Beta worldline in which Mayuri won't die.

A couple days later, an alternate world line variant of Suzuha appears before Rintaro, having arrived in a time machine from the future.

[41] Matsuhara, who was also the producer for Chaos;Head, had previously stated that the game would be centred on Akihabara and that the project with Nitroplus would be the second part in a series around the theme "Science Novels (科学ノベル, Kagaku Noberu)".

These include Eve Burst Error (1995), and most notably the time-travel adventure YU-NO: A Girl Who Chants Love at the Bound of this World (1996).

The Limited Edition contained a deluxe collector's box, a fan book with artwork, a set of replica Future Gadget Laboratory pins, the manual, and game disc.

Due to the way the plot ties the many different events of the game together, Ishii believes it must have been a lot of work to write the scenarios.

[97] Steins;Gate has also been praised by Square Enix producer Tomoya Asano, who described it as having "appealing and likable characters and a scenario that surprised players"; this led to Steins;Gate writer Naotaka Hayashi writing the plot and characters for the role-playing video game Bravely Default: Flying Fairy.

[100] USgamer also gave it a perfect 5 out of 5 stars, concluding that it makes "excellent use of the visual novel medium to tell its story" and "is a beautifully crafted piece of interactive fiction that blends character drama, sci-fi and critique of popular culture into a compelling and memorable whole.

[101] Dealspwn praised the plot, characters, artwork, "excellent" writing and localisation, and the phone trigger system for giving "real choices with huge consequences", and mentioned its technical jargon.

"[76] Syfy called it one "of the best Visual Novels of all time," stating that, while "bad guys exist," "by trying to save the future, you become one yourself", making "choices whose devastating consequences you couldn't predict.

[104] Steins;Gate placed fourth in overall Xbox 360 game sales on Amazon Japan on the year starting on December 1, 2008 and ending November 30, 2009.

[105] The PSP version of Steins;Gate debuted at 2nd place on the Japanese game charts, selling 63,558 units in its first week.

The premise of the game features Okabe Rintaro receiving a D-Mail from himself in 2025 that states that he must save the future by reclaiming an IBN 5100 from a person under the alias "Neidhardt".

This person is Takumi Nishijō, the protagonist of Chaos;Head, as he runs under the same player name in his favorite MMORPG, and the D-Mail stating that "Neidhardt" lives in Shibuya and has "inherent, supernatural abilities", a reference to his power as a megalomaniac.

[117] A third spin-off game titled Steins;Gate Senkei Kōsoku no Phenogram, was released on April 25, 2013, in Japan for Xbox 360 and PlayStation 3.

A CD containing a special Comiket show with Haruko Momoi, the voice actress of Faris NyanNyan, as the guest was released on December 29, 2009.

[135] A manga adaptation of the game, titled Steins;Gate, was created by Yomi Sarachi and serialized by Media Factory in their Monthly Comic Alive from 2009 to 2013, and later published in North America by Udon Entertainment from 2015 to 2016.

A manga adaptation of the drama CD, Steins;Gate: Aishin Meizu no Babel (STEINS;GATE 哀心迷図のバベル, Shutainzu Gēto Aishin Meizu no Baberu), also told from Kurisu's perspective, is being illustrated by Shinichirou Nariie and was serialized in Shueisha's Ultra Jump magazine from May 15, 2012, to January 19, 2014.

[143] A light novel sequel, set 6 years after the events of the original game and titled Steins;Gate: The Committee of Antimatter, was to ship on January 16, 2015.

[147] On July 25, 2010, Chiyomaru Shikura announced on his Twitter account that Steins;Gate would be adapted into an anime television series.

Each set features 2–3 episodes, an art book, and a bonus disc containing music and radio dramas by the Japanese voice cast.

[151] The adaptation was directed by Hiroshi Hamasaki and Takuya Satō,[150] with series composition by Jukki Hanada and music by Takeshi Abo and Murakami Jun.
