Kinda wild to see nobody mention System Shock, the game that invented audio logs. It may seem quaint in retrospect, but at the time all shooters were in the vein of Doom, and story in a shooter was considered "like story in porn." System Shock was not only the first to communicate the plot and next steps to the player through found audio logs, but it also filled the player in on side stories and provided characterization to the survivors on Citadel station.

The game recently got a remaster, and despite very few gameplay changes, still holds up really well in 2024. You can really see the bones of later games in it, such as story focused shooters like Bioshock or F.E.A.R. and I'd really recommend it to anyone interested in playing a great retro game.
