This is very interesting. I'm worse at the modern crap than I am of the historical items of note.
Pretty interesting but I've run across a few errors already. For example, it lists the Spanish conquest of the Aztec Empire as happening in 1 AD but when you flip the card over, it says 16th century.
It's interesting, but it lacks some accuracy. I've hit 13, but it kinda sucks when you "miss" one because it is not correct on their part.
