Despite its shortcomings, the story and the oppressing atmosphere of The Sinking City recommend it as one of the best Lovecraft inspired game to date. If you can get past the clunky combat and technical issues, there's much to like in The Sinking City.
Strictly speaking about the game, I enjoyed the atmosphere quite a lot, and the unique blend of medieval, steampunk and modern elements made the game seem quite unique. The zombie waves and the gameplay in general are extremely engaging, and combat can keep you on the edge of your seat at times, especially when you underestimate enemy forces. All in all, They are Billions is a game that definitely deserves praise, but playing it with anything other than a mouse and keyboard can be literally gamer’s Hell.
