Luxembourg has a lower HDI than Belgium and Germany, so it can't be an answer. The same applies to Liechtenstein in relation to both Switzerland and Austria.

I definitely agree. I guessed pretty randomly at the last couple, and still finished in 1:18. Especially since I knew they had to be countries that didn't border ones I'd already named, I didn't even need to guess at all of the countries. I think 2:00 would be absolutely the most needed, but think it would be more fun at 1:30 or even 1:00.
