As always, the Digital Antiquarian has a great article about this game: https://www.filfre.net/2013/08/seven-cities-of-gold/

on a related note.. talking about tectonic shifts.. might be interesting to have few time-points within same "world", and see how "things" - i.e. continents and such - move around. But that might be a different game
