The Sinking City is Frogwares' latest, and it's the team behind The Adventure of Sherlock Holmes series - a series that's been running since 2002 - most ambitious title to date. It tries to apply the dev's brand of detective gameplay to a sprawling open world setting, for one, making it the longest Frogwares game so far, while this time out it tackle another beloved piece of literature. And the Cthulhu mythos is important to many people because it represents fear itself.
That inexplicable, creeping fear of a monster of godlike proportions has lessened over the years, however, with Cthulhu's rise as a pop culture icon. If you're not familiar with the story itself, you likely at least know the basics, and given that familiarity you feel that Frogwares could have invested in an interesting interpretation of the source material or captured the atmosphere that is all-important to Lovecraft lore.
What you get, though, is another Frogwares detective game, albeit a damp one.
