I am not pleased with the cap on star bases. I only found out about administrators when playing the Mercenaries campaign. I now cannot reach the Drengin!
It seems a silly idea, in my experience hiring an administrator is dead easy, hiring a scientist or engineer is not. My principal problem is building ships fast enough, yes I am probably doing something wrong but limiting a players ability to collect minerals and relics "to favour small empires" appears daft. The game is meant to be a 4X, Explore, Expand, Exploit, Exterminate. Are you saying GC3 is no longer a 4X game? Perhaps you should have called it Small Galactic Civilisations.
Finally limiting the map size is crazy. If my machine will not handle an Immense map then use a Large or smaller. I will now have to use an Insane size map for any future games, which is looking less likely. Space is Huge, really huge, bigger than you can imagine etc. I want lots of space out there. I can then limit good worlds to few, making even size 4 worlds valuble. I want bigger maps not smaller!
