Heavy on the novel and light on the visual: Hate Story is ostensibly a quest for the truth about what happened to the generation ship Mugunghwa, but the ship itself is simply the setting for more singular tragedies. The real goal of Hate Story is to understand the two AIs left on the Mugunghwa and the people who shaped their lives.
Dark in some places, saccharine in others, the tone shifts throughout the game but I never found myself experiencing whiplash... And for a detective story - a mystery, which means you should be kept guessing most of the arc - Hate Story's plot is telegraphed early on. But that you can see the answers coming is not necessarily a negative; not all stories are measured by their plots, instead by how they make the player feel, and Hate Story managed to engage my gooey center. I empathized with not just the AIs but also many of the background characters mentioned in the log files the AIs provide you with.
At the end of the day, whether you would enjoy Hate Story or not has more to do with you than the game itself. It’s a polished experience, but if you don’t enjoy reading for hours at a time or hard science fiction blended with a westerner’s anime aesthetic, than their are other visual novel games out there for you.
I’ll put it another way: Hate Story is about people’s stories, the player is almost an observer for most of the game. You ultimately decide the two AIs fate, but there’s little leeway in the endings, which Hate Story boasts five of them... Except the differences in those endings are shallow and not very rewarding, so you’re playing this game to take in a story and not so much to play an rpg (Don’t expect a paragon or renegade meter to pop up.)
I would recommend Analogue: A Hate Story with the caveat that it’s not a romance simulator (although there is some of that); it’s not an action game (hope you’re not turned off by terminal windows, because_get_use *to-this, and entering commands are as close as it gets to combat); and it’s going to, at the max, last you four to five hours - that’s how long it took me to 100% the game and get all the achievements, and I’m not someone who makes a habit of speed clearing games.
I could say more, specifically about the story, but spoilers are the suck.
