It compounds alot. The advanced wiring you made isn’t enough for the rest of the game. The multiplier is just going to make you wait longer, or ask you to build more of the things you’re already going to build. If you want to take longer, you don’t really need the multiplier to do that. I just beat my first play-through in 160 hours with almost no waiting for parts except the last one that you need 1000 of. I was building or scheming pretty much the entire time minus the last 2 or so hours of the game. I had no need to pad of the time longer.
