I won't knock it if it keeps Firaxis in business to release more Civ games in the future. Long as they don't dumb down the games. Civ6 is at about the right level of complexity.
I fear that is what they will do with Civ VII, make it easier to play on mobile. Heck, not only easier to play, but the mechanics altered to fit a mobile game.
Civ VII mightn't be developed with PC first in mind and an iPhone version later, it might be developed with the limited capabilities of a mobile phone in mind. *shudders*
