Favorite video gaming series have just received the go-ahead for anime adaptations. Some of them have been huge successes because to their use of famous moments, magnificent combat scenes, and great personalities. Other series fall short, especially if anime producers concentrate on a less well-liked or perplexing plot. To honor the creators or fans, or to mark an anniversary, some developers may even pick an old game series.

Regardless, an anime that is based on a game might be a brilliant approach to attract new fans to the series. These kinds of anime may make or break people's perceptions of the original material, provided their plots and characters are well-thought-out.

Updated on October 23rd, 2022 by Olivia Subero: A good deal of anime have manga origins, but there have been quite a few classics that actually originated from video games. Some fans have revisited these titles to introduce them to younger viewers, further expanding the fanbase.

12/12 Some Fans May Not Remember The Fruit Of Grisaia

12 Anime You Didn’t Know Were Based on Video Games_0

Anime fans who love the occasional obscure title may remember The Fruit of Grisaia. The protagonist, Yuji Kazami, transfers to a new school and realizes he's the only male among five other female students. While it seems like a typical harem romance on the surface, it's more of a psychological drama with many disturbing themes, such as assault and cannibalism.

Three years prior, The Fruit of Grisaia released as a visual novel by Frontwing. Unlike the anime, the game contained multiple interactive narratives that wove into the overarching plot. Based on the player's decisions, they could choose how Yuji interacted with each potential love interest, leading to a specific ending. The game could also end prematurely based on the player's options, which could drive the story to an unexpected and possibly deadly conclusion.

Japari Park houses a variety of exotic creatures, now anthropomorphized due to a strange substance called "Sandstar." The humanoid animals are called "Friends" and live happily in their habitat.

Shuffle! is a fantasy-based romantic comedy developed by Navel, first released on PC in 2004 but later on the PlayStation 2.

The anime takes place in modern-day Japan, where gods and demons rule. The kings of both realms move to the human world and befriend Rin Tsuchimi, an ordinary student at Verbena Academy. They have a good reason for this sudden life change: their daughters are head over heels for Rin and will do what they can to win his affection, but the two princesses aren't the only ones fighting over him. Rin's childhood friend, Kaede, upperclassman Asa, and another quiet demon girl, Primula, also have their eyes on him.
