The one thing that seemed odd to me was that Greg had troops across the red-sea ( did it part or did they walk on water ) I would have just maximized my defense in Suez (built the citadel one tile closer to the channel and let Frace puts troops on the tile, not Japan). I would also have made sure one of the first cities was on the red sea and put two or three trimies out. I would have used the trimies and water-walking scouts to cross over to India and do some exploring. Eventually get some cities on the Mediterranean Sea as well; though it is of less importance since you can leave your troops up there and the other three sides of Africa are pretty hard to get to via sea and, even then, no one sub-African region should be that important that you couldn't afford to lose it temporarily during a war. Leveraging Liberty I would have spammed cities to as much as Africa as possible; once Liberty is filled out you're hosed with getting new policies for a while (until you get culture buildings up) but with that much food and production you don't really need policies. Happy is going to be an issue but it should be manageable; we still don't know how #-of-cities scales but a bunch of smallish cities with trading-posts and happy/culture buildings should be sustainable. With that many possible people setup a few production cities and the rest focused on research and go for space. The big thing is not to let Japan get dragged into a hot-war. If France or anyone else wants to attack the citadel at Suez let them; the Red Sea should be easily defenseable (and also added support for Suez) and North Africa can be left for later.
