Hololive Dreams

Hololive Dreams features 54 playable characters at launch. Its characters (referred to in-game as holomems) are members of the Japanese, Indonesian, English, and DEV_IS branches of the VTuber agency Hololive Production. Some VTubers no longer employed by Hololive (colloquially referred to as "graduated") are included in the game and appear in the story, but are not playable. The characters appear as chibis in the game's 3D world and also have 2D models used in the story.

In the story, Hololive-affiliated VTubers come to an oceanic island to open a theme park. The game has main and side quests that expand the theme park and its facilities. Playing the rhythm game and minigames provide materials that are used to expand the facilities. As the main quest progresses, more VTubers come to the island to construct new facilities that fit their motifs.

Hololive Dreams was announced in March 2025 during a Hololive concert, under the codename DREAMS. Cover Corporation, Hololive Production's corporate parent, had the game developed and published by QualiArts, a subsidiary of Japanese media conglomerate CyberAgent.

The producers from both QualiArts and Cover wanted to make a game that is grander in scale than what is generally known in rhythm games. In an interview with IGN, the developers said that the large number of songs were included to stand out in Japan's crowded rhythm game market, also saying it resulted as a natural by-product of aiming to give equal representation to the 54 VTubers. The developers said that the inclusion of minigames and rhythm game elements role in unlocking features were a conscious effort to keep the attention of non-rhythm game enthusiasts. The developers stated that they included cover songs as they are a common appeal in rhythm games and that the covers included were selected to cater to Japanese audiences.

Tyler Colp of PC Gamer described the theme park elements as akin to the series Tomodachi Life. Colp also described the character interactions, such as characters walking on powerlines or being knocked unconscious by falling apples, as entertaining and sometimes leading him to forget that it includes a rhythm game. Colp evaluated it as a "neat way" to learn about VTubers and Hololive, and more comprehensive than other games featuring Hololive-affiliated VTubers. A reviewer from Dengeki also evaluated it as better and more polished than fan games.

The reviewer stated their excitement at seeing their favorite VTubers interact in the open-world. A reviewer for Famitsu, playing at a preview event, found the minigame and open-world aspect surprisingly good and evaluated the game as having intricate details. The reviewer found each aspect of the game enjoyable and said it was well-balanced. The Dengeki reviewer found the game's best aspect to be players ability to create their own charts.
