In my current game, the Invaders have found their way to a system that is not connected to any other existing system. I would like to connect with that system. In the system summary screen it is system 24, and I have most of the systems with similar numbers already explored. (I tried to post a picture of the system summary screen here, but the board won't let me?)
Any suggestions on how to maximize my chances of getting there? Tweaks to Local System Gen Chance and Spread? Other strategies? I'm not above manually changing things with SM, if that's possible. I have "known star systems" turned on. Thanks for any help.
