I know what most of the things are that are shown on this graph. Trade ships, bounty, some techs, etc., but I played a comp stomp with some friends earlier and we have no idea why we gained credits early on. Also, I have a very steady increase throughout the game. The large spike towards the end is from scuttling planets. I've uploaded the recording as well as 10 auto saves in 15 min intervals. If anyone could help us figure it out, it would be much appreciated.
