hmm, its in germany and theres only one team so far, what could it possibly be? actually not every knows that the host teams are guaranteed a spot (that's why crap teams like russia and qatar have qualified recently) so I gues it's fine. I know you'll add to it too.
I know that some countries that are almost in Europe, like Israel and Georgia, are in European things like Eurovision. Just guess every country in Europe, and then do the surrounding area.
Bit generous on the time. Plenty of time to guess every country in Europe & the surrounding area, especially given that the tinies like Andorra are obviously out.
