I can't see what most ships and weapons cost in resources - I go to the production tab and get three columns total, with an unknown amount further to the right. The trading tab where weapons are bought is no help - it only shows a credit cost and whether enough resources are in the storage tab or not. It doesn't show quantity or type prerequisites. While I like the idea, it's hard to fulfill unknown requirements. Is there a table somewhere I'm missing about the costs, or an option to go back to straight credit payment?
If it helps, I play at 1440x900.
