And it was harder than I expected. Good job!
You 2 got to Levels 65 and 67 without ever taking a world cities quiz.
It's generally a good quiz, but if a relatively minor city is surrounded by many bigger ones it becomes a matter of luck.
Overall, it's still fun, but I think making all the dots smaller (and the same size) might help us see where they're located a bit more precisely.
I was lucky to get the most famous cities randomly....
tbh I think NINJAQKk changed something here, now it seems easier, isn't it?
