The series has typically had a fairly good grade when it comes to visuals, but then again, most adventure games focus on getting the look of the game right. The Phantom of Venice portrays the water-logged city beautifully and everything from the gondoliers to the architecture comes through pretty well. While there is nothing stupendous in the game's visuals, it definitely gets the job done.
The game's sound is adequate, but like the visuals, is nothing that really stands out. The sound effects feel appropriate and the general feel of the city seems right. The game's music is subtle and gets the job done, but in the end, it is forgettable. At least Lani Minella reprises her role as Nancy Drew and continues to do a pretty good job.
