I’ve tried to find Japanese horror games from the PS2 era that has this same feel, but I can’t :(
Some quick facts:
The VAs for Siren were British, so every Japanese person had a posh accent and didn’t pronounce Japanese words so well
Siren 2’s main setting, Yamijima Island, was inspired by an actual Japanese Island, Hashima island. The Island was an industrial hub for coal mining and was known for forced labor involving Korean and Chinese slaves.
Both games used facial scans from multiple angles to create the uncanny, and horrifying, expressions of the various protagonists and enemies
I can see that, but honestly, Kuon is just slow and clunky. Deliberately, yes, but way past the point where it can be enjoyed by anyone but the most hardcore fans. The developers overdid it. It’s one of the main reason why the game wasn’t well recieved. To avoid combat you have to play the game the slowest way possible, while the movement is already slow to begin with. At some point the decisions you make in the game are less driven by aspects of the game’s world, but by how much of your own time you want to invest.
When I played it back in the day, I really wanted to like it but just couldn’t, because I felt like the game tried its best to waste my time.
