I would not mind buildings or diorama’s but what size would they have to be to fit with your modelfigures. Obviously the sets from Sarissa in 28 mm or 40 mm are useless for Linear-A sets..
the problem is also what kind of buildings / diorama you would produce, for me they would be Greek or Roman theme buildings, I have no use for Napoleonic or WWI or WWII scenery.
So I guess I agree with most contributors to keep the focus on producing figures sets small and large preferably with large diversity (pre-columbian Indian sets too please and Byzantines!) mostly ancients for me anyway 🤓
And shorter production time if possible, small sets are welcome to for special occasions, for instance with elephants, horses and carts, Inca’s bearing there ruler Atahualpa 😉 sets like that would be very welcome indeed.
