This may seem like an odd question, but how does everyone treat credits in terms of purchasing power? While no two settings would be identical, it helps to know what to charge (even as fluff) for small incidental items and stuff not in the books.
I am trying to create a system for buildings and headquarters and I find I am having a hard time wrapping my mind around what a credit is "worth" when compared to the buying power of say an American Dollar, or a Euro. I keep coming back to roughly a one for one, but this seems like it starts not to work on the higher end.
Any idea?
