Thanks to an update (removed) on the Civilization VI website, we now know that the Firaxis and 2K Games will be bringing the game to the Nintendo Switch on Nov. 16, 2018. There is a high chance that the Switch version would have been revealed at the now-cancelled Nintendo Direct broadcast earlier this week.
Sid Meier’s Civilization VI for Nintendo Switch will include the base game as well as four scenario pack DLCs. The game will also support 4-player wireless LAN. We’ll just have to see if it includes online multiplayer as well.
