Triangle Strategy. I hit a number of points where I had to think hard to make my decision and even then I wasn't sure if it was what I should've gone with. Trying to save and reload to pick something else is futile since I'd just run into another tough decision down the line which modifies things further and it'd take too long to play through multiple key points. It's an amazing strategy game as well.

Yes, your grace, is a great short game

Depends on the kind of games you enjoy.

While not particularly about consequences of decisions, I highly recommend Frostpunk. It always feels like any decision is about trying to choose the less horrible one, but without ever knowing if it will work out or not. The atmosphere of that game is just superb.

War hospital puts you in charge of a WW1 medical camp trying to allocate limited surgeons, nurses, medical supplies as people come in injured from the front line.

Just answer our increasingly difficult questions.

Okay well now the one person is your mom, and the 10 are 1 year olds you don't know

Next level

Okay the one person is your best friends mom and the 10 are young kids from your immediate or extended family

Next level

Okay the one person would cure cancer tomorrow, and the 10 are friends or family

I haven't finished it, but I'd say Vampyr makes you make some difficult choices

I’m not sure I’ve seen it posted here, a little older, but the TellTale Walking Dead games are killer. You make full choices that affect your game later. Tons of fun, not a ton of action gameplay but the stories told are next level IMO

"Passage" is a very short one. But the choices matter.
