How these were matched
Steam tags carry the most weight, because players apply them and they describe how a game feels rather than how it was filed. Souls-like, Atmospheric and Cozy exist as tags and as nothing else, which is exactly the vocabulary this question needs. Formal genres count for less, themes and a shared studio for more.
Tags carried by more than a third of the catalogue are thrown out before matching. Nearly everything is tagged Singleplayer, so matching on it is matching on nothing. That cutoff is computed from the catalogue rather than fixed, so it moves as the catalogue grows.

Common questions
What game is most like Half-Life: Source?
Half-Life 2, on the evidence we have. It both zombie, horror, science fiction, story-rich and atmospheric. That is a statement about overlap, not a promise you will like it as much: two games can share every tag and still feel different to play.
How is "similar to Half-Life: Source" decided?
By overlap on the tags Steam players applied to each game, the formal genres, the themes both sit in, and whether the same studio made them. Tags carry the most weight because players write them, so they describe how a game feels rather than how it was filed. Tags carried by more than a third of the catalogue are ignored: matching on "Singleplayer" is matching on nothing. Every entry below shows exactly what it matched on.
Are these ranked by quality?
No. They are ordered by how much they overlap with Half-Life: Source. Where two games overlap equally, the better received one goes first, but that only moves a game a place or two. Each entry shows its own player sentiment so you can weigh that separately.
What else did the makers of Half-Life: Source do?
Half-Life Deathmatch: Source is also from Valve, and appears in the list below for that reason as well as on tag overlap.
Do you get paid for these recommendations?
No. The order is computed from tag and genre overlap and nothing else. No placement here can be bought, and a game appearing high on this page is a statement about resemblance rather than an endorsement.
