I have a problem with manpower balance right now. Take a lock: Manpower from your capital (On grassland hill, river, next to coast, forest, jungle and mountain) No Policies taken. All avaiable normal building that are neutral or provide manpower. No building build that require improved anything. Timeline: Man | Cost per Wonder Pre-historic: 60 | 2 Ancient: 71 | 2 Classic: 75 | 4 Medieval: 81 | 7 Renaissance: 90 | 11 Industrial: 96 | 16 And then there are normal Buildings that need manpower (some even more than wonders), your Units including Workers, national wonders ... Even with massive cityspamming you'll run out of manpower pretty easy later on. Because you can't demolish Wonders you are stuck with them. This will lead to either hording your manpower because there is always something better to build in the next Timeline, never building anything, or you are stuck in Medieval / Renaissance with whatever wonders you have. Both are not fun. And Civ should be fun. It'll get worse in later Timelines but they need much polish and are really alpha. Just my 2 cents anyway.
