In my mind, the game is substantially better than it was prior to 2.0 or even 2.2 except in one critical regard.
There is too much micromanagement now. If you want to play the game optimally, it actually just becomes “population resettlement simulator” which is really no better than the “tile management simulator” that it used to be.
When they “reworked” sectors, they may as well have removed them from the game. Having to individually babysit 15+ sectors by making sure the each have enough minerals is borderline as much work as individually managing all the planets held by those sectors, because at least the UI shows you when a planet needs attention. When a sector runs out of enough minerals to build things it needs you need to actually remind yourself to double-check constantly, or it will just sit around idle indefinitely with nary a heads up.
The one thing I want back from the old system is the idea that a planet is “finished”, and can be filed away. This doesn’t really happen in the new system, because everything is about population gain and the best use of your late-game homeworld is to just re-settle newly grown pops to small worlds forever. Fortunately there is a mod that does this for you, but there still hasn’t been any kind of solution to the overwhelming micromanagement a late-game empire can suffer that it didn’t under the old economy/sector system.
