I think they did a really good job packing in a LOT of scenery into one server. Good move... don't let the population get spread out too thin until you're ready to expand. That keeps costs down too. The lack of vehicles also makes it feel bigger. Speaking of future expansion, it looks to me like the map was made to be expandable in the south and west directions.
I do enjoy the planet so far. I really like the no vehicles. Gives a much better sense of exploration. Also, how thought was put into keeping costs small (one server) and adding room to expand depending on how everything goes. Kudos. Told many a soc member and have more on the way!
