Almost no one complained that there weren't enough planets last time. For the most part, it was that it was too laggy.Regarding the planet number it was one of the key features why I played the mod. That massive ~150 planets where awesome. I could really feel how wast my Empire was, stretching through "countless star systems". But I just read that the max number of planets will be limited to 100
The performance issues exist because certain aspects of the engine were not made to be scalable - the big one, apparently, being planets per campaign. There's really nothing we can do about this. We're probably lucky it even lets us have thousands of game objects and almost ten thousand hardpoints without dying.
Clone Wars is purposely outside of our timeline. The Republic and Confederacy will never be factions in PR. That's pretty immutable.Clone Wars would be cool, too.
