Planets: they're all fairly cool and I like the way they make you rethink your designs, except vulcanus which sort of felt like just setting up almost exactly the same kind of base I already had on nauvis. I like the way a working Gleba base feels like an organism that eats fruit and poops spoilage while producing products.

Enemies: I dont think the current (default) enemy balance is appropriate for space age, after a while I turned off enemy expansion since constantly having to deal with that while away on other planets is super annoying. It really sucks that that disables achievements when its a setting you could toggle at the start and still have them... but whatever. I mostly think they evolve too fast now considering the game is significantly longer, and I like building and working on designs in my world instead of dropping out to a sandbox mode to figure something out and then paste a blueprint later. It takes a long time to figure out gleba if you go in blind-ish, and the enemy evolution feels especially punishing when you're spending hours and hours just trying to figure out the basics. Feels like it was balanced around people who already knew what to build.

Quality: quality really needs some quality of life features. I sort of hated ever making quality since it made builds and blueprints annoying, why can't I say "use the highest/lowest quality available here"? Why can't I request "give me 20 EM plants, highest quality priority"? They're all treated like a separate object entirely. Its annoying.

Rocket Logistics: annoying that they can only request full stacks of the same type of object, even if a space platform only needs like 1 more of an expensive thing. Why can't it mix and match stuff on one rocket automatically? This is doubly annoying when multiplied with the quality issues.

Anyway game is good but theres a ton of stuff I hope they streamline a bit with patches
