Hidden Object Bundle 4 in 1

This must be the best value on Steam for lovers of hidden-object games. The games are all somewhat old (some only support lower resolutions), but they are some of the best of the genre. Strongly recommended!

House of 1000 Doors: The Palm of Zoroaster

(I played this as a standalone Steam game.) A good hidden-object game, and a very nice, improved sequel to Family Secrets! Taken together, they can be considered one of the better games in the genre. It is quite long and interesting, with a very well-balanced difficulty level, and a wide variety of delightful settings. The voice acting (in English) is horrid, but it doesn't much diminish the overall effect.

Eternal Journey: New Atlantis

Another superb classic, with an epic, imaginative storyline and fun hidden-object scenes.

Dark Strokes: Sins of the Fathers

A superb, classic hidden-object game, with lush graphics and animation, good hidden-object scenes, and a handful of decent puzzles. The story is a cliché, but the excellent presentation makes up for it.

Stray Souls: Dollhouse Story

Spooky, delightfully directed story, excellent graphics, and many superb hidden-object scenes. What more can you ask for? A HOG masterpiece.
