Today i wanted to change some values of the game - but where? 
I modded several games, nothing great, nothing published so i know some things. I've looked into the .entity files - but the seem to be to editable with the editor. Then I found the GameConstants file and thoughed, I found the key... but no, there you can't change the values i'm looking for.
Where, for example, can I change the price of a ship or its build time?
Please help me, thank you!
