Has anybody created a mod that increases the cost of items? I want to increase specifically ship cost by at least 40% to make the game a little more difficult. I want to do this on my server and it affect all the players. In addition, I want to increase the cost of missiles, mines, etc but leave the weapons and thrusters basically the same with only a minimal increase of say 15%. This due to the fact that they can be recovered or salvaged and then sold. The goal is to make it more difficult for players to get better ships. I would also love to reduce the price of commodities say by 50%.

How would I do this on my own if not already done out there? Which tools do I download. And do both the players files and servers files have to be changed or just the server files?
