Somebody should make Sim-15-minute-City. A Sim City-inspired game based on urbanist principles. Start with a desolate suburban moonscape and turn it into a delightful 15 minute city.
There should be a cheat mode that lets you turn off NIMBYs.
@MegaMichelle a point I heard a while ago, which has never really clicked before, is that city builder games almost all set you up to make a car dependent city. You get an unbuilt landscape with a highway off ramp, and the basic infrastructure you can build is streets and roads. As you progress through the game, you can build transit, first buses and only when it's a small city any rail transit. If the game has bike and foot paths they only unlock later to fix the damage from the early game.
@MegaMichelle ... but historically basically no city has ever grown that way. Even in north America, every major city started before cars existed.
A city builder game that reflected that would start you with an unbuilt landscape with a train station or harbour, you'd build streets for pedestrians and horses; as the town grows at some point trams, electric or horse drawn. Then cars and bicycles would begin to appear around the same time and you'd choose whether & how to accommodate them.
@MegaMichelle existing city builders already typically handwave the need for parking lots because they're ugly and sprawl so much 
@MegaMichelle 15 minute Simty...
@MegaMichelle
Then market it to the conspiracy theorists 
@MegaMichelle no need to even make urbanism a goal. Just bake in all the research about environmental outcomes, health effects of isolation and car use, etc. and let people figure out what works on their own.
@george @MegaMichelle Again, with #CitiesSkylines, I think of all the people I saw begging for help with traffic, where every road was at least 4 lanes wide and traffic flow was below 10%. Meanwhile, my city had barely any roads more than 2 lanes, and there were only a handful of traffic hotspots because cars had about 30% modal share.
If people don't think about giving alternatives to driving, they won't find the solution
I haven't played cities skylines, but one thing I've heard about it is that it cheats with the parking almost as bad as sim city. Like, you don't have to put in nearly as much parking as would be required in real life, so cars have a built-in advantage. I've also heard that it models traffic, but people can switch to cars immediately, like a pedestrian just magically transforms into a car, also giving cars an artificial advantage.
@MegaMichelle @george these are both true, and also it despawns vehicles after too long to prevent gridlock. I think all of those can be changed with mods, but I was happy enough with my cycling and metro city. It was delivery trucks that were my biggest problem
@MegaMichelle @trantion @george In the base game you don't build any parking, or have any zoning control over parking - a lot of the land use models have parking drawn in them, so your light commercial zone will turn into a restaurant or shop with a small parking lot. The base game also doesn't have any bike infrastructure (I got a bunch, I think through the "nightlife" add on).
I'm interested in cities skylines 2 but as I understand it, there's no way to even get bicycles in it yet.
@MegaMichelle I did more or less that with my last #CitiesSkylines game, although it doesn't have any explicit 15 minute city target. In fact, people would happily cycle from one end of the city to an outlying village at the other end of the map if you build the infrastructure. They'll also cycle straight over a hill instead of going round, which is a bit of a weak point in the algorithm
