Construction Centers
Another feedback we had was how playing tall was very limited, in the simple fact that every location had one queue for building buildings, and you could thus only build one building at a time, and in the mid and late game, this severely favored those countries with more locations over those with fewer. We had already developed the code for constructing things in parallel with the shipyards, so we decided to add these systems to both recruiting regiments and building buildings. Barracks will allow you to build 2 regiments at once in a location, and the Conscription Center can create 6 regiments at the same time.

When it comes to buildings, roads, and other civil construction, we decided to make it more of a “where do I want to focus on this”. First of all, a city can always have 2 civil constructions at the same time, compared to a single one for towns and rural locations. Most importantly, though, is the new building called the Construction Center, which you get access to through an advance in the Age of Discovery. Each level of a construction center allows another building to be built in parallel in the location. The amount of levels a construction center can have depends on what age you are in, and how advanced you have become.

Just needs tools, masonry, and laborers..
