Hello and thanks for the post. It's encouraging to see the game still being played. I haven't looked at the save but looking at the pictures your colony seems to be winning even militarily since you seem to already have a lot of army and have a good income to buy more. So congratulations on that as any victory is a victory and means something on Apollo.
My 0.02$ and please note I don't want to criticize you very much, take what you like from my criticism but in my opinion this strategy that you employed does not suit the ARC. I don't agree with going wide with ARC but I do understand why you did so in order to try to profit from Aristocrats. The AIs are way too close to your levels in affinity for my liking, with ARC you should be much more ahead. You would/should have been more advanced if you simply focused more explorers and do more expeditions (with Knowledge 2 maybe), and rush Computing faster. Your seeding options are not great either but maybe you are just testing out Aristocrats... and neither are the policies. Prosperity is the worst for ARC in my opinion and shouldn't be opened at all with this faction, ever (edit- or if it's taken, it's only for extra expedition modules, not for colonist). Instead, go all in into Knowledge (expedition science, extra spy) or Might (science from aliens + affinity from techs) while at the same time rushing computing and Spy agency. Industry is also ok I guess and especially so if you like to play with Aristocrats. Early game simply maintain an army good enough not to die, and simply get a huge advancement into affinity compared to everybody, which enables you to win in any way that you like, more comfortably than you are doing in your picture.
I also disagree with taking Developer trait for health since health is mostly useless and especially so if you stay non-wide as you should with ARC. 8 Health might seem like a good idea early game but if you think about it it's a really low amount for how much Diplomatical Capital you invest into it. This trait seems good only if one wants to really focus Health hard in order to get the maximum benefits asap, or when employing Knowledge, trying to keep the bonus science active all times, otherwise doesn't seem to be worth it. Playing with -20 health seems to be ok considering that only beyond this level production becomes affected.
