A possible solution to city snaking
I think I have a nice idea to bring back manual improvement placement as default, without bringing back excessive snaking in the process.
What if improvements didn't expand ZoC? then you'd be limited in your snaking by city ZoC which seems reasonable. ideally you shouldn't be able to use outposts' ZoC to allow improvement building, only city ZoC should count.
Also, removing the "0 mp for passing through city tile" mechanic would mean players are less prone to extreme snaking due to no longer being able to have city highways.
thoughts?
