Wikipedia has a really interesting world list of "Planned Cities" (https://en.wikipedia.org/wiki/Planned_community)

It also has a decent rundown of modern American ones (https://en.wikipedia.org/wiki/Planned_community#Modern_plann...).

You'll have to use your own judgement on a case by case basis if they were successful or not and if they meet your personal definition of master planned.

But I found the lists a very interesting read.
