Country High Points

The purest version of the game: stand on the highest point of an entire country. Some are serious mountains, some are volcano rims, and one is a very pleasant hill in Singapore — but each one puts you, briefly, above everyone else in the nation.

There are nearly two hundred countries, so I don't expect to ever finish this list — but it would be amazing to be able to dedicate the time to it. Someone actually is trying to climb them all: countryhighpoints.com — you should check them out.
