You can use GeForce Now on the iPad (and PC). Recently, all the newer civ games came back to it (after being absent for a few years), so I assume that 7 will also be on GeForce Now. It uses Steam, so you can use all the mods you want.Ultimately, it is the anti consumer Denuvo drm that will prevent me from buying the game. At least for PC, anyway.

iPad, I am not sure. Civ switching could be fixed or at least made tolerable with mods. No mods for the iPad, as far as I know.
