Every Megastructure Explained | Stellaris 

I second this 👍

I agree! There are some absolutely wild Civics that can drastically change how you play. My favorite gotta be Shadow Council combined with the oligarch government. It becomes insanely easy to adjust your strategy and pick the Empire Leader that is suitable for your situation. TL;DR Notice: Please skip to the end of this comment if you don't want to read my reasoning for why I believe Feudal Society is great. This gonna take awhile. Another banger I love is the recently revamped Feudal Society and how leaders basically never have any unity upkeep. Lets say hypothetically you start off as necrophage (+80 leader life-span), Venerable (+80 leader life-span) and then finally Lithoid (+50 Leader life-span); you would have a calculated unity savings of: 5,760 unity per leader. This is on top of not including the guaranteed initial 80 years lifespan of leaders but I decided to not include it as leaders tend to start around their middle years and it can be inconsistent. In an average game of Stellaris we're always going to be guaranteed to employing at the very least five leaders in the initial 100 years of the game. (Four Starting Scientists and a Governor.) We **could** be saving up to a whopping 28,800 unity if we find a way to keep all five of those leaders alive for the full 240 years of guaranteed leader life span. (Not including technologies we can unlock to increase leader lifespan.) Some notes regarding how I came up with these numbers. Not required reading: Monthly Unity Upkeep: 2 Unity per month * 12 months in-game = 24 Yearly Unity Upkeep Leader lifespan: 24 - 50 initial starting age. (Not included in my calculations as it's a variable we have little control over), Necrophage (+80 Leader Lifespan), Venerable (+80 Leader Lifespan), Lithoid (+50 Leader Lifespan) My rudimentary formula for concluding my findings: (Yearly Unity Upkeep)*[Lifespan Increasing Species Traits] = Expected Minimum Leader Unity Upkeep Savings when using Feudal Society TL;DR Feudal Society gives you massive savings in Unity if you can keep your leaders alive. The longer your leaders live, the more this civic becomes powerful.

@@patchpatch4008 Great advice. Thanks.

A lot.

Personally I play wide and aggressive to steal tech from AI to unlock megastructure while being able to afford them but finding existing ones is the fastest because you only need one tech and build it faster often better then ones made
