Yup, a C- at best to Buzztime for an uninspiring set of questions. Whole lot of effort on their part. All they get credit for is avoiding the really simple ones. Couldn't they have talked about landmarks in the cities a bit more? Or brought up former capitals? Or asked which of these capitals is [not] on an island?
As it was, anyone could have gone to the wikipedia list, printed it out, and gotten close to a 15K (or better yet, copy said list into Excel and make two lists, one ordered by country and one by city). Or for the many among us who believe such behavior is not in the proper spirit of the game, at least do as I did, spend 5 minutes looking at the wiki list the day before the game, rely on short-term memory, and do almost as well.
I hope they do better with Baseball Stadiums next week, even though I almost certainly won't be able to play that one. Weather permitting, I will be researching the subject matter firsthand
