Soma was really good, and certainly worth playing if someone likes sci-fi and single-player FPSes and this subject matter, but there are some fundamentally frustrating things about it. Number one for me: in contrast with something like Half Life, you play a protagonist who speaks and has conversations about the world, and is also a dumbass. The in-game protagonist pretty much ends the game still seemingly not understanding what the hell is going on, when the player figured it out hours or days before. It's a bit frustrating.
