Generally speaking, the conventional wisdom is that you only want to found a city on a resource that a) is a pretty bad tile improvement, e.g. elephants, incense, etc., or b) is a resource you don't want to have pillaged, e.g. oil or aluminum.
Didn't uberfish settle on a plains hill near, but not on, the gold mine in Epic 4? I seem to recall that he did quite well keeping up in research as a result.
One nice thing about the resources--and I include the floodplain as a resource too--is that they are on the same side of the rivers as our citadel site! That might mean the barbs will attack them by crossing the river, thus incurring an attack penalty.
I think an immediate switch to Mysticism is the way to go. With some luck, maybe the obelisk will bring Copper into our city's cross before too long. At least it will give us some flexibility for the placement of our next city, if we have to found one.
Looking at the warrior, it's tough to see how it will be very productive in the next few turns. This is largely because the hill has revealed a lot already and the tiles north and east look like mostly forest, which won't be a good extremely-early-game resource. I guess just NE, NE, NE then reevaluate to reveal as many squares as possible, since we'll want to expose as much land as possible to find Copper when we get Bronze.
For techs, my thought now is: Mysticism, Hunting, Archery, Mining, Bronzeworking, Pottery in that order. (Maybe Pottery after Mining, I'm not sure.) Unless we discover another food source in range of the plains hill, improving either the Rice or the Sheep is only going to give us a +2F tile, and with the floodplain and the rice, we've already got 2 +1F tiles to work for growth. A Granary will probably get us just as much food as improving the tiles. (Note: I might be wrong here because of health cap issues. It depends on how many forests we have.)
Note: to get another +1F from the rice, we'll need to farm the square north of the sheep on the river after Civil Service. But that's a long way away right now.
I think the build order in Osaka should be: Obelisk, start Worker, Archer (when Archery completes), finish Worker. But I'll probably want to shadow-test that build order. Depending on when our worker techs come online, it might be better to complete the Worker first.
@regoarrarr: Did you queue up workboat, warrior, workboat in Kyoto?
With the Gems, our happy cap in this city will be 5, just like our unconnected capital. Improving the rice and building a granary will give us just as much health as improving the rice and the sheep. That leads me to think that Agriculture should be after Pottery above.
Final note: Now I can see why one team posted a save after just one turn!
