I primarily play single player so I don't know if this is a issue with multi player or not. I've noticed that in single player that there are always other empires in the same star system as you even if there are other systems. For example I created a random large game with 3 star systems and with just myself and one other empire. In the setup screen I tried having the computer player being in the spot directly below me and all the way at the bottom and a few tries in the middle. Regardless of where I place the AI it always starts in the same system as me which leaves the other two star systems empty except for pirates. I would seem to make more sense that if there are three systems and three players they should be spread out evenly over the are available..... Not sure if this is a bug but it was something I noticed.
