This is "me-too" deck with the nations of the world, their capitals, flags and the internet Top Level Domain (TLD) code. The TLD code is what you often see associated with IPs, like .us for the USA, .mx for Mexico, and so on.
I liked the other deck of the nations, but it was simply too random to learn the nations in an orderly way. When you're trying to remember a capital of a country you've never heard of nor do you know where it is on the map is close to impossible. I also found myself stripping out a lot of cards I found to be a bit esoteric for general study, yet it was missing the TLD codes. Also a lot of the images were mangled or unclear.
For this deck, the cards have been grouped by continent. You can try doing the whole deck at once, but from experience I'll suggest you do them by region. Presentation order is identifying country by map, then country + capital, then country + flag, then country+TLD. Items are random within categories. 199 independent countries are in the deck. This does not include countries still in a struggle for recognition. I thought about adding national leaders (presidents, kings, prime ministers and the like) but this is far too transient.
If you get something out of this deck, please rate or review.
