That depends on what kind of games you like and what you're in the mood for playing, of course.
I bought
Dark Fall: The Journal in a sale like this and I kind of liked it. It's a first person point-and-click adventure game where you move from one room (or spot) to the next, you can turn left and right and inspect your surroundings and interact with them. You'll discover journals, notes etc. to read which will tell you part of the story or give you hints on what to do and how to solve the various puzzles you'll find. I've never played any of the Myst games, but I assume it's in the same vein as those (another game you could compare it to is Scratches: Director's Cut). When I played it, I also made lots of notes and drew me a map of the house - it's not required but it helped me remember all the locations and hints.
So all in all it's a more or less static puzzle game, don't expect much action from it. But if that doesn't put you off, it's an enjoyable game with nice story-telling and good atmosphere, best played at night with the lights out (it's nowhere near as frightening as Amnesia or any other real horror games, just a little creepy due to the immersive sounds and graphics). I guess you could play through it in less than two hours, maybe even just one if you know what to do, but it took me several nights to read, think and figure everything out, so if you enjoy ghost stories and puzzle-solving you'll get your money's worth.
