As I understand it, the random seed set up at the beginning of the game will cause the planets to generate the same each time (including terrain, POI's, ore deposits, etc.). I've encountered a situation where that does not quite seem the case. I tried the same seed on two different computers, and while all seemed the same I noticed that the depth the first POI I encountered was not the same on both machines. I tried again one the second machine and found the depth to be consistent. Is this to be expected?
That's a possibility. It seems that shouldn't matter, but I'll try to check when I can look at the one on the desktop.
