Second paragraph of third chapter:

But India is also home to some of the most iconic games of all time. If the Middle East gave us one of the best racing games, then India is the birthplace of one of the greatest war games that humans have in-vented: the game of chess.

An outline of 80 classic games from the mathematical point of view, framed as a voyage around the world to explore the games of each continent and subcontinent. Unfortunately this framing turns out to be a bit problematic, as he sort of has to ignore the actual geography and the history of colonialism to make his points, whatever they are. There’s a weird five page chunk near the end about women writing games. The bit about Azad seems oddly familiar to me from elsewhere. There’s some very interesting material here, but I think it could have been much better organised, and the researchers whose work he has, er, depended on could have been given more credit. Still, you can get Around the World in 80 Games here.
