This was a pleasantly addicting game. Obviously, knowing the countries helps a lot (except that time it identified a place as being in Norway, and it turned out it was some island they owned in the south Atlantic Ocean). But unless it's a small country, there's still plenty of room for skill (and luck). And it is an awesome feeling squeezing out a passing score because you actually do know exactly where Ushuaia is.
Fortunately, I was able to squeak out a victory on my fourth try, so it won't suck down any more time I hope.
