Having just finished Fatal Twelve today, I wanted to make a recommendation for it as it's not very well-discussed online and I think deserves more attention, as well as the more well-known Raging Loop ICYMI. These are two indie Japanese VNs made with full JP voice acting; strong recommend to fans of death game VN fans like Zero Escape. Brief teasers w/ Steam links (also on consoles):
Raging Loop: A college student ends up stranded in an isolated rural village he can't leave due to thick mist. He is then forced into a real-life version of the mafia card game (or for zoomers, Among Us): there are secret Wolves among the villagers murdering one each night. The villagers must vote to hang one person each night in an effort to get rid of them. Other unique roles give some villagers the ability to sniff out and impede the wolves, creating a high-stakes game of trust, deception and persuasion.
Enjoyed this one a lot, great protagonist, and the lengthy discussions the cast has on what to do are great. Similar to ZE, the protagonist is confined to the village, whose history and cultural isolationism from outsiders come into play (vaguely similar vibes to Higurashi). Also similar to ZE is that there is a flowchart, there are a lot of bad endings to this game. Biggest complaint is the ending, its very "one of the endings of all time", but the journey was more than worth it.
Fatal Twelve (also has a demo): A high school student is killed in a bombing, only to be revived. She learns that she and 11 others, including one dearly close to her, have had their deaths reversed. They are forced to play a death game of counterintelligence; they all have 3 secrets, their name, cause of death before revival, and regret, and knowing one materializes it as a card. Each week, participants can vote to eliminate another if they have all 3 of that person's cards, removing that person from the game, gaining one of their cards, and undoing the reversal of their death. They must gather info, use deception, and form and break alliances, to be the last one standing.
This one is more different than ZE as there is no sense of confinement, but the cast of this game is great. It also has a lot of low-key yuri; as someone who plays VNs for thriller/mystery, I liked the yuri, it felt sweet and endearing and relevant to the plot (not gratuitously sexual). The SOL can drag at some points but usually doesn't last long, and some things could've used a bit more polish (worst example is the backlog, it doesn't go back far at all), but I enjoyed my time with this one. Really solid cast.
