Paradox keeps ignoring everything that was achieved by its own titles. No Europa Universalis diplomacy - a swarm may devout all galaxy without any unified responce whatsoever, no Hearts of Iron logistics - you just doomstack all your fleets in a single system, no Victoria economy - your population, instead of being statistical number, is presented to you as a bunch of actual units on a planet, which not only produces tons of lag, but also is very strange from simulation perspective, and is not helpful in any way from economic planning point of view.
