However, if we move 4 SE, it'll be distance 6 from the capital, that is almost too far to be considered first-ring status. Even distance 5 is already quite far for my taste, don't know how high corruption will be there. I usually settle at 3-4 and never have problems in getting 12 tiles for all my core cities. Also: there are many hills but only few food-tiles. I'd much rather settle on a hill there, than on grassland. (The defensive-bonus can't hurt either, as it'll be on the Viking-border for quite some time.) What I find quite extra-ordinary in this game: the Vikings researching Writing! I've never seen an AI research Writing at such an early date! However, we can hope that they will go for Map Making, as this is a favorite tech for the AI and as they are sea-faring. And it looks like there aren't any huts in this game, so there's no risk that someone pops Philosophy from a hut. So I would still take the risk and go for the "full sling", even if we are quite late for Writing.
