Finished playing: Soma (2015)
I'm going to be honest and say that I didn't complete this one outright. I stopped playing about halfway through and simply watched the remaining plot beats on YouTube. I thought the premise and environmental design in the game were top notch, and I appreciated that its horror was more atmospheric and existential than jump-scary.
Unfortunately, I found the pacing to be deeply unsatisfying, which is what drove me to stop. I felt like the game was giving me story and background through a slow dripfeed between lengthy fetch quests and scene changes. I got significantly more enjoyment out of the lore from the wiki, discussions, and timelines that I read after the game than I did from experiencing/uncovering them in-game.
I will say that, knowing what I know now, it probably would have been worth downloading a savefile close to the end and picking the play back up, as I think the last act of the game would have been genuinely great to experience first-hand. Nevertheless, I don't regret watching it, as that cut out several hours of tedium for me--tedium that likely would have ended up turning me away from the game completely.
While it wasn't for me, I will say that I think the devs made something special. It felt like a playable Black Mirror episode, there are several powerful story moments, and the setting-induced dread is palpable (and only grows!). It's not that I think it's a bad game--it's more that I personally didn't love playing it.
