I like how the game has progressed since last time I played, but I'm confused about the planetary revamp. What was the reason? Less micro and better AI? Not sure about that, but I'm glad the geographical (adjacency and what not) tile management is gone, even though I miss the presentation and the "tactility" part of it (in that you could drag pops around - I take it there's an auto best fit now - which is fine). Yet, now there can be hundreds of pops and variable density (which wasn't modeled before).
The economy part of the game has improved a lot, and I like the challenge of balancing/adapting the budget for dynamic needs (e.g how far can you push efficient alloy production and if you can increase living standards in the meantime). The trader enclave trade of previous versions might have been the worst feature of any modern strategy game, but the new market has completely remedied this. Not sure how the price mechanism works though, but it's as if the galactic empires are minor market players due to relatively small dynamic perturbations on a seemingly set equilibrium price (unlimited supply somewhere - but I guess one could be set based on galactic resource availability). Maybe there would be too little trade to achieve stable markets with only 10 partially trading empires or so. Piracy and trade is much more convincing now as well.
Securing resources is a good incentive for war, but the market could have an even bigger potential to that end if it could introduce competition, embargoes, and interface local markets.
The AI still lags behind. Year 2400 fleets are still less than 20k. (Everyone except the FE are rated "pathetic"), and now got a War in Heaven on my hands. The biggest AE has fleets rated at 90k for a total of 600k. I struggle with a fleet cap of 280 and probably 60k fleets (maybe settle for anti admin cap tech stagnation toward end game?). I guess I could have played even more aggressively to have a go at the Non-aligned achievement, but would be a senseless fight currently it seems.
The L-gates are much harder than people make them out to be. I had to go multiple fed+mercenary (cannon fodder)+regular+allies+dual titan rounds on massed 250k fleets. Small picket vessel swarms are good diversion, but some ships just got to pack a punch too.
Space communism is now a thing (and makes sense where slavery, feudalism and capitalism does not - as reflections of modes of production tied to obsolete non space faring tech : ). The empire voice over is a bit on the paradox-humorous side though.
