It's all of a piece with the return of vinyl (out-selling CDs), artisinal everything (beer, booze, food), americana music, etc. People are yearning for something more visceral, more tangible, less disposable. It's almost like every micro-brewery needs a game or two in the corner to provide that little bit of extra ambience.
Time will tell if it's just a fad. But nice to see while it lasts.
