I've already seen them suggested, but I want to throw out another recommendation for Signalis and Lunacid . Signalis is a sci-fi horror game that takes heavy inspiration from the old Resident Evil and Silent Hill games. Like Resident Evil you have limited ammo, inventory, and points where you can save. Like Silent Hill you have a story that starts out fairly straightforward and then gets weirder as things start to unravel around you. I'm not really a survival horror fan and it still managed to keep me hooked to the end.

Lunacid is a first-first person dungeon crawler that is heavily inspired by pre-Dark Souls Fromsoft series like King's Field and Shadow Tower. That's really all the game sets out to be and it absolutely nails it. The combat can be a bit repetitive, unless you invest in magic which I found to be incredibly fun and versatile, but I feel like the atmosphere more than makes up for it. It also has a ton of secrets and plenty of those ah-ha moments where you open up a shortcut or figure out how one area connects to the others.
