A bunch of the pictures in this thread have shown those end-cap style walls. Where the fieldstone is 1 size and the a much LARGER size at the corner, transition, etc. Any stone building has this - and it's AWESOME

There should be a details mold that allows for transition - preferably BOTH into (gothic) chipped stone and ALSO into the large corner blocks. That would make all the regular buildings look 10x as classy.

Round molds are just going to make more turrets - and we're not all making castles here! BUT--a transitions/decorative corners mold would be dope.

In addition, someone asked for blank signs - why not window inserts? A few different shapes, even if they were integral to the tiles surrounding them, could do that shuttered leaded glass old world window. Then, if we're really shooting for the moon with a two tone (ala large corner blocks) fieldstone construction on the first floor and a half timber (another use for those insert-able windows) for second stories. Voila! Medieval town...
