The parents' guide to what's in this game.

Positive Messages

Game has unexpectedly deep focus on emotional issues many people deal with and ways they cope with those issues and how doing so can lend them strength. That said, some issues discussed are shockingly dark and not handled in any healthy manner.

Positive Role Models & Representations

Main characters in the Go-Home Club understand that they're not in a real world and begin to come to terms with their emotional issues. Protagonist works to establish, build friendships with his or her fellow students, helping both in the process. There's a story path, though, that allows player to essentially betray his or her friends throughout the game.

Ease of Play

Gameplay's fairly complex, requires a lot of menu navigation for everything from dialogue options to skills and equipment to maintaining relationships with 500+ students (and potential party members). Combat is turn-based, giving players time to plan moves, which also show potential outcomes. Players not only choose actions and abilities, but also can adjust timing of their execution for best possible results.


Characters spend a lot of time fighting against possessed students, other enemy bosses. No blood or gore in combat, with defeated enemies collapsing, vanishing. But there are scenes of death, as well as implied incidents of abuse, suicide, other forms of violence in flashbacks, dialogue.


Some female characters presented in provocative manner. Also provocative lines in dialogue and text message conversations between player and other students. Other unique situations arise due to fact that all the characters are portrayed in Mobius as high school students, while some are much older (or occasionally younger) than they appear in the "real world." Finally, some gender identity issues are addressed in potential story arcs.


Some characters frequently use profanity in dialogue and text messages, including "s--t," "ass," and "bitch."


Game is an expanded remaster of original PS Vita exclusive The Caligula Effect. This version includes higher-resolution presentation, downloadable content (DLC) such as character costumes, other brand-new features not found in original.

Drinking, Drugs & Smoking

Some characters make passing remarks about alcohol in game's dialogue and text messages.

What parents need to know

Parents need to know that The Caligula Effect: Overdose is a role-playing game available on PlayStation 4, Nintendo Switch, and Windows-based PCs. The game is an enhanced remake of The Caligula Effect, which was originally an exclusive release for the PlayStation Vita. This new version includes enhanced visuals, all previously released downloadable content, and new story-based features. The plot's primary focus involves people attempting to escape some emotional trauma and getting trapped in a virtual world as a result. This leads to a number of sensitive subjects as they uncover the secrets the non-player characters (NPCs) are hiding, such as suicide, abuse, alienation, and other heavy mental and emotional situations. The game's dialogue includes a fair amount of both profanity (including "bitch" and "s--t") and sexual innuendo, as well as occasional references to alcohol. While there's a steady stream of violence in the combat portion of the game, it's not graphic in its depiction and doesn't show any blood or gore.

What's it about?

THE CALIGULA EFFECT: OVERDOSE is an updated remake of the original PlayStation Vita exclusive The Caligula Effect. The game's central focus is emotional trauma and the ways we cope with the pain it causes. After an encounter with a mysterious being called "μ" ("Mu"), you begin the first day of school as a second-year student at Kishimai High School. But things take a disturbing turn as you learn that nothing is what it seems. You quickly discover that nothing around you is real. The entire city is a virtual creation designed to offer people a life without pain, without anger, without sadness. It's a fantasy, and you're not alone in your realization of this. Together with the other students as a part of the "Go-Home Club," your goal is to defeat μ and her "Ostinato Musicians," freeing yourself and your fellow students from this false paradise ... and learning to cope with the personal turmoil that brought you here to start with.

Is it any good?

Escapism can be both a blessing and a curse, but this game attempts to bury its problems deep and pretend they don't exist without dealing with serious topics in the best way. The Caligula Effect: Overdose has something oddly inspiring about learning to harness emotional pain to turn it from a weakness into a strength, but it's also strange that the game's story sometimes treats such heavy topics as death, abuse, bullying, and more with an almost cavalier attitude. In the story, the characters exist in this virtual world to escape the personal and emotional traumas they've suffered, but even after learning their secrets and facing what brought them to Mobius, these issues feel like they're just swept under the rug.

Even putting aside the psychological aspects of The Caligula Effect: Overdose, there are some difficult issues for the game to overcome. For starters, the game's repetition is almost mind-numbing. The entire adventure is set in an incomplete virtual city, with most events happening on the high school grounds. Most interactions are with students that, outside of the main cast, look and act like filler. You're meant to build bonds with these characters, but they've got no real personality to bond with. In fact, the texting feature is just a series of pre-programmed and random questions, which never come together like any actual conversation. The game's combat system does feel like something genuinely unique, with players choosing their party's actions, adjusting the timing, and even seeing the potential outcome before locking everything in. It's an interesting system with a lot of potential that it never quite lives up to, leading to fights that wind up feeling overly long and drawn out. It adds to the game's overall feeling of repetition and monotony, making The Caligula Effect: Overdose an experience that will make you want to escape back to the real world as much as the rest of the Go-Home Club.
