I've you've ever played video games, you've certainly encountered a number of "elevator rides" – points in the game where you either enter an actual elevator in a game, or walk through long tunnels where nothing happens, that sort of thing. These elevator rides have one purpose: to give the computer to catch up and load all the stuff in the next level or area of the world, which is why they often take 10, 15 seconds in which literally nothing happens. And, of course, this means that switching between levels or areas is super annoying, and you try to avoid it as much as you can.
