I'm new to Stellaris, well I've had the game a while but not played much. When creating my empire at game start I choose Clusters thinking this means they will start in a spread across the galaxy. My last three game starts have been aborted because I have empires all over me hemming me in and stopping expansion. So clusters must obviously mean empires start next to each other, which is just frustrating. It seems to me a grave game design flaw not to have the empires spread out. It there any way that I'm perhaps missing that forces the game to do this?
