Ghost Files 2: Memory of a Crime
This sequel has a lot content but falls apart due to exceptionally awful voice acting and an incomprehensible story.
Once again you are a detective, but there's nothing supernatural about the mystery this time. The gameplay is polished enough, but because the story doesn't make sense all your actions feel more tedious than fun.
Also, the "True Grit" achievement didn't activate for me even though I did not skip any of the minigames, including in the (awful) bonus chapter.
