Sacra Terra: Angelic Night [Collector's Edition]

This is one of the best hidden-object games on Steam and should be played by any fan of the genre.

The game is gorgeously painted and animated, and though the story isn't especially deep, it's well told through the visual mood and gameplay. The scenarios aren't very diverse, but they fit together to a convincing whole: you will get to know the mental hospital quite well by the time you finish the game!

It's nice and long, with plenty of perfectly balanced and pretty hidden-object scenes, and a decent amount of non-trivial point-and-click adventuring. The game's only deficiency are its mini-game puzzles: there are very few of them, and they are all far, far too easy.

All in all, it's a satisfying way to spend a few hours for those who enjoy relaxing, atmospheric, visually appealing games that demand only an attention to detail.
