I am a big fan of escape rooms. The basic premise is, you are locked in a room and need to solve a series of puzzles to get out, perhaps to another escape room. There have long been virtual escape rooms. My favorite of these is The Room series on iOS.
The linked article explores some real life escape rooms. They range from pure puzzle sets to a more theatrical presentation. Personally, I’d love to see a video game that marries the best of both worlds: A multi-player implementation of an escape room that gives you a virtual presence in an escape room, a real social experience.
