Ultimately, we can probably tech at a parity to the best civ in the game using any two of the Pyramids, Collosus and GLH. Pyramids gives us that extra 3 pop in IS, JD, FC OO and one other city, probably AC/Angle, and an extra 3 bpt from each specialist, which when we go full on tech gives us something like an extra 60 bpt, going through cheap libs, which is 75 beakers every turn (ie, this is just from rep, the basic scientists give us another 75 beakers), which then going through the tech boni, which if all three of MS, Cav and Kaz have the tech, and we have 1 optional prerequisite, is an extra 106 beakers every turn. But this is arguably the easiest wonder to get, it only costs 1 GE. It also does require any expansion to make use of; if we capture Angle and use that, then all we need to do is to grow IS, FC, OO and Angle to max size and work scientists, but if we do that then we can't expand at the same time. So to make full use of the pyramids asap, we need to get out as many workers, settlers and basic fogbusters as we can now. We will have CK to build stuff, but that isn't really capable of alot by itself. As it is, if we were to try to expand asap to ALL city sites on our peninsula, then we would be building workers and settlers for a fair while, so we need to find a good balance between teching and expansion later on, and the best way to tech later would seem, ironically, to expand right now to the coastal sites and grow asap, leading me on to: Collosus, we have 9 to 10 coastal cities that have between 7 and 10 sea tiles each, and at least 1 food res. If we accept that we can tech fairly well of just scientists, then working just food and 2 coastal tiles in each city pays for the maintence in each city at 0% tech on the slider (in sims, we vary around 20%-30%). FC and IS work between them 12 coastal tiles at max size and bring in an additional 40 base commerce compared to not working the coast (Collosus adds base 10), and basically increases our overall base commerce by between 20%-30%. This is enough to let us save gold at 0% tech and hence we can tech off the slider to a small amount. Both FC and IS can grow to size 12 with rep and gold, working all of the coast to grow, so they make us alot of commerce so long as we do grow them, and at size 12 they can also work the majority or all of the hills, and with the blocker city and Angle (and the rice near IS), we have enough health for both cities to reach that size. We can get the Collosus in either FC or IS. It's easier to get the Collosus in FC, we can get it sooner, and it gives us just enough time to get out some extra workers from IS that we do need to speed up the settling of gold city and then return to chops jungle in JD, which is a city that shortly will need alot of worker attention (not only does it need cottages, but we need to mine both of the hills to get the forge done). Getting it in IS does strengthen IS as a GP pump, but we may be better suited to using AC/Angle as the GP pump, as IS is just a much more powerful production city, and we are going to have to be as efficient as we possibly can. The GLH is just a way to strengthen the coastal cities grab, even if it only gives each new city 2 commerce per turn at the cost of 7 turns worth of production, with all of th coastal cities settled, that's still 20 commerce per turn, so that's another 2 city sites that we can afford, or another notch on the slider every few turns. The cost isn't prohibitive by any measure, and should provide at least a 3:1 return on our hammers (3 commerce for 1 hammer, minimum). The biggest problem with the GLH is that it might fall by t95. If this happens, so be it, we wouldn't have invested anything in it (we need the lighthouse in IS anyway), and we would be able to get out 7 turns worth of other stuff aka another settler workers and chariot/axe escort. Which teams would build it: Kaz are teching and probably wouldn't build it in time unless they go for it in their capital, we wouldnt see it until around t100 if they go for CS, so it would be close. Cav, no idea, they probably could turn Their cap into a wonder city, with Org Rel, but they'll probably wait for bureaucracy to change, and their capital isn't exactly the most powerful city in the world (hell, it's hitting at most base 20 hpt, probably close to base 15). MS...don't know what to think, with onyl 4 cities and 3 food res, they have much more pressing matters than trying for the GLH, but that wouldn't stop them doing something so stupid, and the same holds for Saturn.
