Alone in the Dark | PC
The original AitD from 1992 was my first horror game and one of the first PC games I ever played (being a console kid before that). I don't know if I ever made it past the first few floors of the house before giving up, probably because I was a huge scaredy cat. I've picked up a bunch of stuff like this from the 90s on GoG over the last few years meaning to replay or finish my childhood favorites and never really touched any of them until now.
Like a lot of those games, it's just a Dosbox wrapper around the original, and I don't think it does any graphical enhancements like some other emulators do, so you're looking at a pixelicious upscaled 640x400 in fullscreen, or a small window which you'll probably be in since you can't alt-tab out without windowing the game.
AitD has a fun if corny story about a haunted estate with a long sordid history with the occult and Cthulu. You play a man or a woman with different motivations for ending up at the house, but with the end goal of trying to get to the bottom of all the weird and crazy goings on in the house. Through manuscripts and books you pick up, you can read the backstory about the house and all the previous inhabitants, with some mildly terrible audio readings that you can skip over. There are a few simply puzzles, a maze, and a bunch of enemies like zombies, spiders and ghosts that you can either fight or escape, but the real test is fighting the control scheme. The character moves and attacks very slowly, with bad camera angles that sometimes completely hide the action or where you're trying to move. You use WASD to move, and the left-right arrow keys to aim and the up key to fire, or all three to perform different melee attacks. It takes some getting used to and is never anything but annoying.
It was fun to go back and finally finish this one, but I can't imagine anyone getting much out of it unless a die-hard horror fan interested in an early classic or someone like me looking for a nostalgia trip.
