Resident Evil 1 Remake. One of my favorite games of all time. The mansion is the most iconic place in RE in my opinion, the level design is awesome, and Iove the replayability of the game. Unlike other people I also enjoy fixed camera angles. Only thing I dislike is having to watch the door loading screens each time you go through a door.
Besides RE1R, I'd say I like the original RE1, RE2, RE3, RE4, and also RE7. Their respective remakes are good (except for RE3), but are all lacking something fromt the originals, like cutting important areas or drastically changing characters etc. RE1R, however, included everything it should from the original and then added more good stuff which made it a such a good remake as well.
Another horror game I like is Silent Hill 2. I know the gameplay is shit, but the atmosphere is top notch and soundtrack is perfect. It's not my favorite though because of the said gameplay.
