One short addition: if you can spare a galley, send it to explore the border between Mongolia/Germany. Most probably they are disconnected as well (after that disappointment with Greece
). In that case we better leave them alone...
But if they are connected, then they might be quite weak by now, so could be an easy target after Greece. Otherwise you are right: Egypt looks like the best target for the remaining Greek veterans. I think, with Greece, Incaland, Persia, Egypt, America and perhaps one more, we should have the missing 700 tiles you are talking about.
For gaining the other 500 tiles "at home", remember what ignas said: "settlers are better than temples". I think that's right in many situations. A settler costs 30 shields and gains app. 15 tiles immediately (if placed correctly). A temple costs 60 shields + 1gpt and only gains 12 tiles. (The second bump is hopefully out of reach...) A temple should be necessary only in a few cases, where a couple of tiles can't be claimed otherwise.
The cases where a library is necessary (for a faster second bump) should even be more seldom. If we can trade Lit, ok. But it's certainly not worth researching it for that handful of tiles it might gain us.
But otherwise your plan to let the corrupt towns build settlers, sounds good! In 30 turns we may hopefully be close to that 700, and then the settlers will be "ripe" to gain the rest. (If we are faster on the "military" side, we can cash rush the settlers after 20 turns or so.)
But we still need settlers now for our attack and resettling purposes. So I'd say: re-activate a settler pump somewhere, and in addition in strategically important cases we just cash rush a settler right at the point where it's needed.
