I finally watched that video and it indicates that Firaxis hopes to release the two big expansions to the Switch by the end of the year. Since the Switch version can do cross-platform cloud saves with the Steam version hopefully that should allow for greater parity and being able to play with all of the big content when switching between platforms. So hopefully some good news on that front. Will be nice to be able to play this and Divinity Original Sin 2 interchangeably between PC and Switch on the go.
…now back to your regularly scheduled endless QT3 kvetching about Civilization. ;-)
