We're planning on doing a pass to have building titles better reflect what they do. (Like Hydroponic Farms should probably be the "flat jobs" building, while "Food Processing" should improve the jobs.)
But there's also the fact that since building slots are limited, and not based on how many times you upgrade your districts, spending building slots on flat jobs instead of modifiers seems like it's usually a bad idea.
Seems like something that will teach new players bad habits. Especially the fact that you start of with an Urban zone and three flat jobs buildings is a problem in that respect. Right now the optimal strategy seems to be to tear out the basic factory and build an Industrial zone to actually get an economy going. Then, once you get planetary unification, rip out the other two buildings and Urban Zone, building a Research Zone and a Unity Zone.
Having to delete your starting buildings and zone is not at all an intuitive process for new players.
In that sense:
All of the combinations that we added in this pass are either one or two zones. However, one of the changes that I've been considering based on feedback is actually removing one City Zone slot from planets, increasing the free Government Zone to have six building slots, and framing them more explicitly as City Specialization. While this is similar mechanically to "forcing" an Urban Zone, it may make the intent of "zones are intended to be your way of picking what special district you want here" more of a real thing.
Might be an improvement in not teaching players the wrong way to build an economy.
But, you're still not reconsidering the forced specialisation of colonies to a limited set of resources?
I just started a new game, currently it takes 10 years to complete my first set of techs unless I start seriously scaling my research production. At first, at best I can build an additional research labs building, but that's not much. So obviously a research zone is necessary, but that also requires a Industrial or Factory zone for scaling CG. As it stands currently that requires either Planetary Unification (Which might take 8 years) or colonising another planet.
That still does not feel natural at all. And "getting another colony" is not an option for quite a few Origins. Reducing the possible number of zones to two will make this even worse, making these Origins utterly unplayable.
