There's an old video game called Seven Cities of Gold wherein you play a european explorer poking about the new world. It has procedurally generated game worlds, and claims to use some plate techtonics. I don't remember if you could actually circumnavigate the world, but it gave a great experience of gradually uncovering an absolutely massive map, packed with things to see. Designed for platforms with SERIOUS technology constraints, the author packed a LOT of game play. Given the historical subject, it also offers up some serious topics for thought / conversation.<p>As always, the Digital Antiquarian has a great article about this game:
