In Polygon‘s review of Civilization 6: Gathering Storm, it sounds like the expansion pack won’t be coming to iOS. I find this incredibly sad because I love the game and I was looking forward to Gathering Storm. The iPad version also doesn’t include the Rise and Fall update which came out last year.
So I’m going to just say that if you’re looking for a better, more advanced, more complicated Civ 6, then Gathering Storm is just fine. But if you’re looking for value, if you don’t want to feel like you’re being gouged and punished for being a fan, I’m inclined to suggest you wait for a price cut.
