i don't know how the buildings works at higher research levels (i guess it's only a difference of product numbers), but it would be a lot nicer to be able to do more than one activities in the same time. i mean i'd like a farm to produce wheat and hops at the same time, or a furniture factory to produce wooden furniture and picture frames not one or another. i don't want this at level 0 (it would be too easy), but for a lot of money it would be nice.
