What have people's experience been with the new map types?
Can we see some screenshots? (I am especially interested in the Big and Small script)

I was always frustrated with the maps in Civ IV, and I would usually go with Snaky Continents or Terra. But Snaky was often too watery, and Terra is simply too much for most games! I'm hoping BtS delivers the goods!

Really, of all the features in the game so far, I am happiest with the new map scripts (specifically the Big/Medium and Small).

Makes up a lot for the rather poorly implemented espionage.
