A strange little side quest
Even a quick game like Top Floor Room sits on top of decades — and sometimes centuries — of ideas. The first crossword puzzle book appeared in 1924 in a cautious initial printing of 3,600 copies, complete with a free pencil. The surprising part is how quickly the next milestone followed. Computer Space reached arcades in 1971 and became one of the earliest commercial electronic arcade games, even though its controls proved demanding for many players. That gives Top Floor Room a little more company than it first appears to have.
