I had hoped that Rise & Fall would address the game's late-game doldrums, but perhaps they're saving stuff for a full-blown expansion that will, among many other things, introduce railroads. The whole game should really change course with the Industrial Era. Civs that fall behind would be in trouble, even if they were "winning" up to that point, but we can see in the real-world that some civs were capable of catching up. The Ottomans didn't, and sank, but Japan and later China roared back. It would add some much-needed dynamism to the late game, which is a drum I've been banging since about 3 weeks after launch. I don't know why the game is so timid, but maybe the devs are saving their fastball for a big, late-game DLC.
