It's a great game for wrecking people's shit! One of my favourite things to see.
You're in luck if you liked its themes because questions of personhood are very popular in scifi.
The problem with me recommending anything is that, as I said, I'm not hugely into the gameplay of SOMA, which means that if you liked the gameplay specifically, I can't recommend anything for you -- I'm sure similar games exist but I haven't played them. I'm a turn-based strategy, simulation game, and walking sim kinda person.
If you like those genres, though, boy do I have some fun scifi recs for you. All of these are available on Steam, which is where I get most of my games.
Citizen Sleeper gets the gold medal for Vibes. It's one of those games that I want to blank from my memory specifically so that I can experience it from the start again fresh. Being the Sleeper was an Experience.
Silicon Dreams leans hard into personhood, memory, and autonomy, and makes you confront such questions again and again. Unforgettable experience. When I woke up in the chair I had heart palpitations.
The Talos Principle is great if you just wanna focus on the philosophy of personhood. Like SOMA, it's all very basic and doesn't require any prior philosophical education or real familiarity with science fiction of this kind at all. Incredibly accessible level of discussion. Also, puzzles! And there's a kitty cat hidden somewhere in the game.
Digital: A Love Story probably won't wreck your shit, it's hardly cutting edge scifi and philosophical deep cuts, but it is fucking adorable. It's set in the near future of 1988 and it's fucking adorable. Its sequels are also interesting enough in their own right but very different in theme.
To The Moon, Finding Paradise, and Impostor Factory belong to a series that gets deeper into themes of memory, identity and personhood as you go. I recommend playing all of them in order. To The Moon doesn't have much in the way of these sorts of personhood themes, but it is a fantastic game (even if it gets facts about Animorphs wrong :( ) and contains necessary backstory and setup for the other two.
Minds Beneath Us is a fantastic little game I just finished that does have these sorts of themes of personhood, although it doesn't dive into them nearly as hard as it could and goes for a different surface story instead. They're there, but light.
Subsurface Circular is a great little game that plays on personhood, service, and inherent limitation. Also you're solving a mystery! That's always fun!
The Turing Test is also great for this. Made me motion sick as all hell though, so if you're prone to simulation sickness, keep an eye out for that.
It's difficult to know whether or not to include INSIDE on this list, because INSIDE absolutely is a game about humans-as-consumable-product, and an absolutely brilliant one at that. Beautiful game, wonderful presentation, unforgettable experience. However, the abstract nature of the story makes it hard to know whether you'd consider the experience of playing it to count as what you're looking for. It is a game that forces you to put in effort to engage with its themes, and you can play through it without engaging at all (although I imagine it would be a very weird experience if you did).
Similarly, OneShot is a game where these themes exist in the background, in the lives of the robots and the concept of "taming", but they're part of the background setting, not necessarily something you're required to engage with.
If I don't mention Thimbleweed Park or Doki Doki Literature Club, somebody will complain, so here they are, technically on this list. But. I think these games were bad. I think they did a really sloppy job and dropped the ball at the end so spectacularly that it retroactively poisoned the entire experience. Doki Doki fans don't @ me.
Again, I should re-iterate that the gameplay of all of these games is very very different to to SOMA. These are mostly walking simulators and puzzle games, with the occasional rpg or detective game in there. If you're looking for SOMA-like gameplay, you'll need a list from somebody who prefers those types of games.
