The thread is quite large at this point, so sorry if it's been recommended already. GRIS is definitely a very emotional game. It's quite short, probably on sale quite often, visually stunning, and very sad.

Slime rancher always makes me cry at the end, but it deffo requires you reading the random notes and emails, and then also giving a shit about characters you never actually interact with. I can’t remember why it’s so emotionally effective, but this is the exact trap that keeps leading me back to replaying it and crying at the end again.

I played Heavy Rain and somehow managed to get the ending where everyone died. That kept me off gaming in general for quite a while. Brothers was mentioned here, I can recommend it too. Papo y Yo is a allegory of your relationship with an alcoholic abusive father, and it didn't make me cry outright but was pretty heavy.

How has A Plague Tail not been mentioned? Most of these mentioned a good games with a sad scene or two thrown in. Plague Tail, especially the sequel will make a grown man ugly cry.

Yakuza 0. That ending. Bruh.

Try SIGNALIS ! It is extremely depressive, emotional and evocative, and to an extent it is a homage to stuff like Silent Hill 2

My first thought is definitely Valiant Hearts: The Great War. That one, I found, to be devastatingly sad. Regularly on sale for super cheap, including right now. Also available on mobile if you prefer

It might not fit entirely in, but check out Spec Ops: The Line. It's more or less linear shooter, but the story (and ending) makes it quite unique and very different from any other game I've played. Could too get pretty emotional at times.

They probably aren't your cup of tea but thought I'd add some more variety.

Final Fantasy XIV; an mmo with focus on story and the story arc from the past 9 years is wrapped up and brought me lots of tears.

Honkai Impact 3rd; ARPG gacha game (I know, I was skeptical) also with years of story following a relatively small cast of characters.

Detroit: Become Human had a really great character focused narrative where basically everyone can die. Give that one a go

Ori and the Blind Forest? I know it's not quite as mature as some of the things suggested here, but it really knows how to hit you hard at some points throughout the story.

Portal 2. But you should play the first part before sequel, if you haven't already.

The Last Day of June is quite lovely.

The House in Fata Morgana. Nice thing is that'll it be both sad and happy tears.

It's been a few years and listening to the soundtrack snaps me back. I only wish I could I could play it again for the first time.

Rakuen was the most recent game I played that did that for me

The ending of metal gear solid three hurt me pretty good.

S.O.M.A has a moment.

Don't think I've seen anyone mention Oneshot. Amazing little game.

Have you played Plague Tale 1 and 2? I'm not considered a very emotional person, but the dynamic really got to me. Just a really solid game, enjoyable combat. They're two of the very few games I binged to completion.

Papers, Please. Maybe not crying, but could definitely put you into a depressed mood if you manage to get into character. Needing to make a choice between letting some poor bastard's wife follow him without proper papers and feeding your family is tough.

It was short and sweet but Planet of Lana got me in the feels a little bit.
