Oyzar, you forgot about HC, he starts with myst and is financial. He is also industrious, so instead of a worker, get a head start on stonehenge for the GPPs. And a shrine is great. If your religion spreads to just one other civ that builds 5 cities and you build 5 cities, that is 10gpt, twice that of a settled GP. Once you have writing EVERYONE wants open borders. I would chop a monastery and whip missionaries like crazy before the borders start closing or someone grabs Theocracy. If you spread to every city in a civ and they don't have another religion in all there cities then they usually switch over to yours.
@Gaiur who said "These 15gp are a myth, that works only on Pangea, I think. On standard world size it will be difficult too." I play standard size continents or Big/small maps. There are usually between 25-30 cities on a continent. If you spread aggressively you can get 20+ cities with just missionaries from one city. even at just 20 cities when you build a marketplace that is 25gpt. That is usually good for a notch or two on the science slider, by the time Beauracracy rolls around you can have a GS for your academy in the capital. And more of that capital commerce can go into science since the shrine is paying the empires upkeep.
And on higher levels the Ai spreads religions very fast, even if they aren't the founder. Pop your religion in their capital before someone else does and they will spread it for you. Or you can just spread it to their cities that already have a religion.
I used to check my shrine gold and adjust the slider accordingly so that I don't spend it. That can keep me even with the Ai in techs with some shrewd trading and still build up a stock pilefor upgrades. The problem is....if you have a lump of cash....somebody is going to ask for it, so either give it to them or have them hate you 2000 years later because you didn't. So now I spend it as soon as I get it.
