The common meme among Civilization fans goes that it takes two expansions for the newest game in the series to be up to the standard of its predecessor. So, it took Civilization IV until Beyond the Sword, and Civilization V until Brave New World for fans to be happy with those games.
Civilization 6 came out a few years ago, and it was a great game, but it ended up removing quite a few mechanics from Civilization 5’s Brave New World. The first expansion for the game, Rise and Fall, was a marked improvement, but ask any fan of the series, and they’ll tell you Civilization 5 is still better. Going by the meme, then, what the game really needs now is the second expansion.
That second expansion may be coming—the YouTube channel for the series has posted a brand new video livestream, titled only ??? (You can see this video for yourself below). The timing suggests that a second expansion for Civilizastion 6 may be imminent—hopefully it is as much of a revelation as Brave New World was.
