Global Diplomacy (GD) and Age of Discovery (AoD) are two variants of a wargame, run by E-Mail Games. The games simulate strategic level warfare and diplomacy at a late-19th Century technology level. The smallest units are of corps and squadron size.
Whereas Global Diplomacy (and Global Diplomacy 2) attempt to simulate the geo-political situation on Earth, around 1880, Age of Discovery uses a randomly created map and is slightly different in regards to some rules.
