Crimson Room was one of the pioneers for the Escape Room genre.
I really love the Rusty Lake series. It has a unique style, a great atmosphere and returning characters and exciting mystical plot elements. The developers, two guys from the Netherlands, let themselves inspire by Twin Peaks. But one can also see some influence from the Buddhist philosopy in their games. The stories are really deep. The developers got really successful durinf the last years. Last year they made a combination of a game and a movie.
Another good inspiration is the submachine series. I don't know if the developer of is still active. Submachine also has very mystic and dark plot.
My point&click inspiration mainly comes from classics like Monkey Island & Indiana Jones. But I also like the Daedalic games like "A new beginning". I like games in a realistic setting. More or less realistic.
