Material cost option.

[Ultimoos]

This idea is mainly for randomly generated worlds. I'd like to have an option in world generation menu about material cost.
For example. For this world I'm generating I want all items to have material cost increased x2/x3/x4 etc.
Why idea like this? I have a feeling that player progresses in game a bit too quickly. With all that automation, it's hard to keep up even with a couple of miners. Cost increase would give players more time to think about designs and explore terrain.
