Weird Park Trilogy
Excellent value for fans of hidden-object games and casual point-and-click adventures. The three episodes are a bit repetitive in style, but together provide many hours of fun adventure. I strongly recommend it!
Weird Park: Broken Tune
(I played this in "Hidden Object Bundle 5 in 1".) A classic HOG, with good scenes and gameplay. If you play it in expert mode, you will get quite a decent point-and-click adventure that requires logical thought. The background story is spooky, but doesn't take itself too seriously, and there a few jokes. Fun!
Weird Park: Scary Tales
The clown returns. The background story is simpler this time, but you will get some variety in scenes as you travel between multiple fairy tales.
Weird Park: The Final Show
An excellent finale to the series, which brings closure to the clown and Mr. Dudley's story. This one actually includes achievements! (Though they are not linked to Steam.) I did find a few "string not found" bugs, but nothing serious that impairs gameplay.
