This is part of the Twisted Skyscrapersim video series, using "Random Activity" checkbox was checked, where simulated people were using the building and making it seem busy. Which floor was pressed first, I had to get off at and wait for another elevator, though elevator stops without the button being pressed did not count. Most of the waiting in this video was cut out for time purposes.
Any suggestions for the Skyscrapersim Twist series? Let me know in the comments section below!
