>I have Infra in my cart and I'm pretty sure I'm going to buy it but I was looking for some more suggestions while the sale was on
Infra is great, but it REALLY isn't a detective game, not even close to that. It's an urban exploration game, the gameplay revolves around documenting decrepit infrastructure. There is a mystery plot behind it, but you don't really do anything to piece the story together yourself, the game is a strictly linear experience and more info on the pseudo-conspiracy behind it is just dripped to the player via exposition.

One game that actually may fit your interests is Pathologic 2. It's mechanically a survival game, very hard and dreary, but it has a murder mystery subplot, and one of the most brilliant journal / exploration / investigation mechanics I've ever seen in any game, ever.
Again, it's not thematically your conventional detective game, but the way you build a literal network of clues, decisions and reveals is essentially a very mechanically satisfying investigation process.

Man I miss the days when IPL games were a fairly regular subject of discussion here.

It's kinda horrifying to watch how... far we have gotten from that now.
