An old game called Sim Tower was pretty cool in that your success as a huge tower builder was directly linked to how well you could optimize elevators. There was a maximum number of elevators that you are allowed to construct and once your building gets large, if you don't optimize, people will get fed up with the waits and abandon your tower. The game allows you to setup different patterns for different times of the day. It allows you to set wait floors, set which floors it will stop at, and even set patterns like skip to the top and drop off on way down. This last trick avoids the problem of needing to stop on the same floor on both your way up and way down, which would occur with normal elevators if say the elevator was taking two people up, one to floor 17, one to floor 20, and someone wanted to get on at 17 to go down. In all the game was really fun (although construction was repetitive), and does make you think about elevator optimization for the rest of your life, I played it as a kid, and I am always thinking about how badly elevators are optimized!
