It's in a category called "Africa & The Middle East", which has only 3 entries, just like "Australia, New Zealand & the South Pacific". I might make a quiz about "The Rest of the World", which could also include "Mexico & Central & South America" (at only 5 entries).
New Delhi is on here but not Seoul? Istanbul? Dubai? Jerusalem? Chiang Mai? Patong? ... all of those places are better. Delhi is Asia's sweaty butthole.
Jerusalem at least is in the section "Africa & The Middle East" and if this hadn't only 3 entries I bet Seoul and Dubai would be there too. Istanbul is in Europe, according to the Travel and Leisure guys.
