Thompsons: To further elaborate on my own post, the problem with Personal Nightmare and Waxworks is that they're adventure games that get a little bit right and practically everything else wrong, and are probably the most insidious things I've played in the entire genre.
Personal Nightmare is creepy and a straight-up adventure game without the stupid combat system of Waxworks, but it runs on a time limit with certain key events and items being missable, along with tons of really obtuse puzzles (the reason one of the screenshots is "HIT DOG WITH STAKE" is probably cause GOG realized nobody in their right mind would guess that solution on their own) and hideously screechy DOS soundblaster noises. There are also a ton of really worthless items to fill your very limited inventory, so good luck figuring out which mundane object you need to pass so-and-so puzzle.
Waxworks is about as bad, if not moreso because while it still screws you over with puzzles and hangups (all but like one scenario has moments where you can explicitly reach a dead end without any warning), and it adds a clunky combat engine which basically amounts to "click, click, click on enemy and hope for the best; reload previous save if you take too much damage." Yeah, it's pretty spooky, but so what if the gameplay itself isn't any fun?
You know what's more fun than playing either of these games yourself? Watching someone else play them. In fact, here:

Much better than just calling them stupid and terrible. ;)
