It's good to see that the flip-tiles series is being added to continuously.
I wonder what will come after
Looking at Dungeon, it looks like it has connectors for caves, urban, grasslands(maybe forest?), and sewers. Looking at Forest, there seems to be connectors for river, road, magic portal?, and Dungeon.
So my guess is Caves, Sewers (Might be expansion for Urban), River, and Road
