It may sound a little condescending, or like I’m bragging about something as elementary as putting on my pants or brushing my teeth, but I wouldn’t say that this thread is entirely unjustified either considering how so many adults are (almost) clueless about the subject.
It took me only 0.5–1 hour(s) to master this, and any frustration that I had was minor.
I play geography mobile games sometimes and it’s pretty illuminating. Knowing where every nation is already puts you leagues ahead of most westerners in basic knowledge of Afrika, which is pretty sad. It’s worthwhile, though, for sure.
