Don't forget AOE4! It's really a great evolution of AOE2 - more unique playstyles per civ, has about 1/2 the playerbase of AOE2 but still plenty to play online and support its own pro scene (was also in the Wololo tournament).
I wouldn’t call it an evolution. The game might be good in its own right but its different in some very fundamental ways besides the historical setting. Especially on the competitive level.
