Surprised to not see mixed zones mentioned. Always wondered why that's been left out of the game, but zones with mixed residential/commercial purpose are very common, i.e. small shops with apartments on top - these should not generate as much noise as low density commercial and provide very few jobs. Also a few more pedestrian options: wider sidewalks and zonable pedestrian roads, stairs/elevators/escalators or whatever small footprint ascension mechanism, connect tunnels to metro stations and overpasses onto rail platforms.
Hey illuminaut, and welcome. Mixed use buildings were certainly discussed before, trust me. I believe they weren't implemented because the engine wasn't capable of handling people living were they work and vise versa - just a product/limitation of the engine I suppose. I'm still hoping for a workaround too.
I would love to see something like that.
I live in an apartment above a shopping center myself (a complex of about 500 people)and in the old city of Zwolle, there are hundreds of combined commercial/resi buildings.
I can see my apartment from here....
FWIW I know only 1 city building game that did that as a standard game feature.
Civ City Rome. They allowed you to build a type of house, which could be "upgraded" with a shop.
The basic game mechanics (assets and building them) are completely different though.
It's more like a resource manager then a city builder anyway.
But yeah. Housing above shops would be great.
