How do these figures effect things in the game for any given species? On the Race detail screen there is a box that has a list of characteristics such as Diplomacy, Exploration, Trading etc. and a number in the box next to each, in SM mode I can happily alter this number and save it for the race. But there is no pop up to say what these numbers represent, are they a percentage increase in things, or a static figure increase or some arbitrary number left in from a previous version? Also what does each of the characteristics do in regards to game effects?
