This was a really interesting quiz! I spent two minutes trying to figure out the last answer, but I almost missed Indonesia because I thought I had already guessed it... but I did it with 8 seconds to spare.

I mean, Peru is the 19th largest country in the world, and it's coastal, so it wasn't a horrible guess. I guessed it too towards the end.

I still think that Greenland shouldn't be included, if it doesn't count towards any of the other "biggest area" quiz. Cool quiz though.

I think there should be a note marking that autonomous regions count, since I almost missed Denmark. Also, I think its cool that even small countries like PNG can get on it due to their islands.

It mentions overseas regions but not specifically autonomous regions. So I would interpret that to mean France is included but wouldn't assume the Kingdom of Denmark is, especially since it is seldom included in Jetpunk quizzes.

Kazakhstan really shows how much influence the sometimes very fractal coastlines have here, when you see how much higher on the list significantly smaller countries like Norway, the UK or the Philippines are.

Yes, and this must be why Algeria is not on here (the largest land-mass country in Africa), and yet the Democratic Republic of the Congo is.

also greenland shouldn't be counted on this quiz because yeh its a part of denmark, but it makes it look like denmark is giant. Also how is greenland this high when its smaller than libya

Coastline tends to be very faceted while land borders are generally straight, which would explain why Greenland exceeds Libya (even with the Mercator projection helping Greenland). And your first sentence doesn't really make sense. I could say that Alaska should be left out of the US because it makes the US look large, but that doesn't have any logical justification.

I'm surprised France and the UK aren't highlighted in gold. I mean, in both cases, the mainland doesn't have that much coastline compared to, say, South Africa, does it?

(Yeah, off to "realsizeof" I go, or whatever that page is called, to compare them with the Mercator projection turned off... I need to get me an old-fashioned world globe!)
