Besides the declined vassalization of Hector Alvarez, a lot of quiet builder's turns. We should get all 4 of the targeted systems, although Duat does not currently have a garrison (and Kurnugia needs to keep the PDS that's 1SE of it). I've built some missionaries, to spread Knowledge and Religion around a bit. Our cities are primed to explode in population: unlike Civ, your food surplus tends to INCREASE as you grow in size. Even with the rapidly escalating food costs, our larger cities grow in fewer turns than the smaller ones.
I have sold ours maps to everybody. Across 8 AIs, I can cover most of our deficit with sales from a mere 1 or 2 new bomber recons in someone's territory. We also have a lot of open borders now (6). The AIs are not teching well, and I figured that their gold should fund our research. Terrestial Networking comes in next turn.

Demographics:

I think we're winning.
Tech situation:
Our tech situation:
I think we want a starbase here for the oxygen:
Our current cities:

Most of those builds are brand new, so please feel free to veto. We could build wealth or shorter builds in many places, since next turn we get Commercial Satellites (+2 commerce on a planet!) to build everywhere.
FYI: Please delete Anti-Ship missiles when they are created. They cost upkeep. Including the Pacifism gold. They're far too weak (less than a single bomber strike) to keep lying around at 2gpt each.
Upcoming tech choices:
Shock and Awe: (with that lovely picture of Rumsfeld): If we want to begin gearing up for war, then this and Capital Ship Focus should be our next two techs. Shock and Awe only really gets us Battleships, kings of the stars, but Capital Ship gets us Delta Invasion ships, Carriers, and Capital Ship Doctrine (-20% cost to Battleships, this is the one I usually take when I'm building a fleet).
Mechanized Workforce: Delta Starbases (useless, since the build starbase command builds regular ones only. If the AI could threaten a starbase, then the upgrade might be worthwhile), and Delta Anti-Ship missiles are rather useless. Mechanized Workforce is +10% hammers in all cities, but -1 happiness in our largest 6 cities.
Environmentalism: Research Labs (+25% research, 80H. With Knowledge, and very few planets having built a second University, we don't need this yet). Green Economy: -20% commerce in all cities, but +1 to the pop cap of every single planet. This will be a fantastic civic once we've outgrown our planets if we've got the happiness.
If we want a Mechanized Workforce (with Religion floating around, gems coming online soon (T147?), and Sports Arenas left to be built, I think we can take the happiness hit), I say we go for it. If not, let's take the military techs so that we can build some offensive units. Regular Battleships and Delta Invasion should hold their worth for quite some time. Another option would be to head for jump lanes (railroads), the tech after Mechanized Workforce. We'll need some more workers (I didn't build any, didn't see the need), but RRing up to our targets is necessary on a map this big.
