Did not like this HOG much. A lot of the objects were near the bottom where you could not see them correctly. Also most of the objects were combined ones, meaning you had to find several parts to get them to count, which most of the time did not really make sense. And the placement of the HO scenes did not make sense either, as well as some of the puzzles were missing instructions shrug
Seems to not have aged well.

Slightly better than the last one, though finding all the pearls was annoying as hell. Also the fact that some of the items are hidden in containers without it showing them to be in containers was annoying, since you have to randomly click on stuff to find the ones that open.
Some of the minigames were annoying since they made you repeat a certain thing for like 3 minutes straight. Which was not really fun.

I played the first two entries so far :

FBI : Paranormal Case : An FBI Agent (who thinks he is some kind Fox Mulder) investigates some weird happening that turn out to be bubblegum chewing aliens.
Each scene has to be revisited 1-2 times with a few standalone rooms. Some translations where horrible. Took me about 3.5h to complete it.

Hidden Files : Echoes of JFK : Better gaphics then the last one. Faint white arrows to guide your gameplay, which unfortunately blend in with the background most of the time. Story was a weird conspiracy theory about the JFK murder. You can collect some files/information about JFK. Took me about 3h to complete
