Just made my system! There's a total of 4 distinct races in this system, including myself: The Remnants of Sol.
I don't know how to feel about this start though. I created the system, the races, mineral deposits, etc. Before 5 days were up, there were already a bajillion ships flying around and I didn't even have a fighter up yet. Fortunately, none of the ships attacked me (They might not have been able to, because I'm pretty sure they were all beam ships and so they couldn't attack my planet, and there certainly weren't any warships around.)
Using one of my warships that I cheated in (sorry lol, wouldn't risk that hour or two of setup time just to immediately lose), I destroyed a squishy, one armor unit vessel with ten size 9 missiles. Nice. This has actually really helped me understand how to use the combat mechanic.
Once I blew up the vessel, it launched life pods and am currently sending out a few ships to pick them up. How do I interrogate POWs that I got from the life pods?
My only problem with this save is that it takes forever to do turns, not so much because of the 3 different NPRs in my system, but because they're constantly fighting, so I'm only able to go at 5 seconds turns every now and then and that's super obnoxious, especially when I'm a bit of a way away from the enemy ships I'm trying to hunt down with my beam cruisers.
