The closest thing I can think of is Minecraft, which IMO is a 100x better game but still you can't play it forever. People loved the creativity of it, but even more they liked the idea and the story of the creativity. How many times did you see in a feed that some kid made a computer in minecraft, a display, a life size battleship or tv spaceship. I am sure people see those stories-- think I could do something like that-- and go back to the game. The dream informs the play.
