There are now over 20 Nancy Drew detective games developed by HerInteractive based on the popular teen-girl detective books.
In my opinion one of the best of the Nancy Drew game series is Nancy Drew: Warnings at Waverly Academy. The suspenseful atmosphere of this game is initially created by being set in a girls’ boarding school, where gossip, rumor, pranks and secrets are rife. This setting also works well in developing the storyline, the characters and the types of tasks you have to do in order to solve this mystery. The quality of the graphics, interactions with the other characters and dialog, which have improved since the previous games, also add to the atmosphere. And the puzzles and gameplay itself are highly enjoyable and reasonably challenging.
There are many excellent Nancy Drew games, but this is one of my favorites!
