A lot of characters in the game mention getting loans to pay for mods or ships and such. I also noticed that whenever you are given credits that it mentions getting transfered into an account, but based on the nature of credits it probably isn't a bank account, otherwise you would probably get some kind of interest at regular intervals. I thought that what if there was an in game bank location where your character could get a loan, that if you miss a few payments on or don't pay off in a certain period would result in a bad end, or open a savings account where the interest increases or decreases based on the amount deposited. I'm not a writer, but I thought this was an interesting idea and I wanted to put it out there.
