No particular order, also I'm grouping some of them together because no one can stop me:
Half Life series (yes, even Blue Shift)
Monster Hunter series (but mostly World)
Abiotic Factor
Prey 2017 and the Dishonored series
Fallout 1, 2, New Vegas, and kiiinda 4 (with some mods installed)
Honorable mentions: Songs of Conquest, Path of Exile 2, Neo Scavenger, Team Fortress 2, Dark Souls 2, S.T.A.L.K.E.R. series
