Unnecessary crafting time. I don't need instant crafting for everything, but some games take it to far and it serves no purpose other than to slow down gameplay. Im playing through Scap Mechanic right now. If I want to make a car, I need to craft bearings for the wheels. Each bearing takes 30 seconds and I need at least 6 for a car. Not to mention the crafting chain of basic materials that you need to get the things needed to craft the bearings all take 20 - 30 seconds each. It can take a couple of minutes to craft from start to finish. I can't be waiting around all day for my stuff to craft.
