Bakony, Croatia & Slavonia, around Kaposvar

 
Western Hungary, with a large flat plain and good farmland throughout, a fairly middling population and next to no heavy development.  Even Kaposvar, with a population above 5,000, doesn't rate a type-1 hex.  Mozsgo, in Alfold, was generated last time I was mapping Hungary.

The large body of water at the top is Lake Balaton.  Some may be familiar with in on maps of Europe, but it's going to look quite different here.  Wikipedia discusses how the lake wasn't developed until the 19th century, when the swamps around the lake were filled in.  As such, I'll be using the guideline shown in the attached diagram, reading the old shoreline from GoogleEarth to get details.  The part shown on the map above is the middle bottom on this diagram, slightly to the left of centre.

The expanded lake should look positively massive in this scale, forming quite an obstacle.  My original research on Bakony shows it to be something like the Saskatchewan of Europe, though obviously a lot smaller.  Viewing the next area over, it should look more or less the same as the above, with more of Balaton added.

The lack of topography makes it much easier to get these sections up more quickly.
