Well, in reviewing the save I can't see too much that hasn't already been covered. I am wondering if we should just stick out the research on Plastics. Giving Catherine Ecology lets her build another SS part. I realize that will push back our earliest launch date by 5 turns but I don't trust Catherine to let us beat her. In this same vein I was trying to figure out what our launch date would be. The way I figured it (trading for plastics now)
London York Beijing
T-0 SSE SSC Research
T-1 SSE SSL Research
T-5 SSSC SSL Research
T-10 SSSC SSL Research done start Docking Bay
T-15 SSSC Done SSDB
T-30 (1845AD) Done Done Launch
This is based on ~1,493 Research/turn (calculated from current rate, I didn't do the math to figure out what the actual rate per turn is, as there must be a small overflow. According to the city screens we are earning a combined 1,332 beakers/turn) This also presumes the same levels of research.
Production is based on current city output. It doesn't look like there will be much change unless we were to use the GE to complete IW or we allow Liz to start it and we gift the GE to her. But there aren't any guarantees what she will do with it. London will grow by 1 Pop but even assigning that Pop to a Engineer will only contribute 2H/turn and 3B. Liz will probably not get another GP before the end.
Using GE to cut research on Robotics will trim off 1 turn or less.
Using GE to rush IW will increase our Hammers by 50% which will boost research and SSDB when we get Robotics. Taking into account the health penalty, and having to work the coast instead of a PH, it should still cut 2 turns off the completion time for the SSDB.
Finish date was calculated at 5 Years/turn. When does it switch to 2yrs/turn?
Catherine has 7 cities, at least 5 of which are "good" cities. She also has DPs with Cyrus and Saladin. Does anyone remember when they signed their DPs? If Cathy signs a PA with either one, we may be left on Earth. Checking all possibilities, no one can be bribed into DOW Catherine.
I am somewhat worried that LIZ may be attacked, and as a result stop producing SS parts. HC has quite a sizeable force in Athens and is feeling lots of cultural pressure. He is annoyed with Liz and these two factors may be enough to make him DOW. We should consider upgrading our units in case they are needed, we have more than enough gold.
It seems we can still sign a DP with Cyrus. As he has a DP with Cathy, this should keep all enemies at bay. Something to think about? If Cathy has DPs with both Saladin and Cyrus, she isn't likely to attack them.
Now I know I have probably miscalculated, missed important game mechanics, and just plain botched the calculations, so please take a look and let's discuss it.
but still +1 
overall.
