GalCiv I veteran here.. but I'm new to GalCiv II and I am still trying to nail down this new tile-based-planet idea. Is it truly the best method to completely specialize my worlds? (1 for only tech, 2 for only money, 2 for only ships, etc). And also, for my ship-production worlds, is it advisable to use the majority of my tiles to build factories? Or is it a waste to build more than 1 factory per world? Thanks for any advice.
