I need to say this, I think too many people think horror = scary, or a horror game needs to aim to be scary. There's some big misconceptions people have on what horror is, and isn't. SOMA is most definitely a horror game, but horror can be combined with anything, it's the opposite side of the coin to comedy. Horror plays on peoples darker fascinations and often has a a thematic role as well. Sci-fi and Horror get grouped together a lot since their themes often collide, but sci-fi is a thematic, like fantasy, while horror is tone that can be applied to anything. Even the 'horror' games that we know proper are just tones attached to other already established game genres, ranging from adventure games, action games, etc. Some thematics over time get added to the definition of horror as they get recognized as such, but it is a horror sci-fi game, it doesn't need to be one or the other, it's both. Scariness is subjective anyway, horror can get a scared reaction out of people, but being scary is not what horror is actually about at its heart. A similar thing can be said for comedies, where a comedy can make you laugh our loud or smile, but there's other things comedies can do and still be a successful comedy even if it isn't particularly funny. One of the strengths to being a fan of horror or comedy is that they can literally be attached to any sort of thing, even each other (horror-comedies), and yes, there are certain themes that come with horror and feelings which develop, horror gets typified a lot simply because too many successful works in horror get copycated until it becomes a staple (even in horror games, but it's happened in all forms of horror entertainment), but I dislike how people tend to be like, "Yeah, it isn't really a horror game, because it's not scary." Some of my favorite horror games of all time I don't particularly find scary, but while being scary can be a nice plus sometimes, horror and even good horror isn't specifically tied to how scary it is.
