My thoughts are: with so much food, no need for quick pottery. Start on max research on masonry for Worker Housing asap (settling on hill gives 2 shields, the Oasis gives one, need one more for bonus to kick in, plus extra happy means more income). Or do we start with Masonry? Need to check.
Build Scout, Champ, Scout?
Move settler N, NE, then settle next turn if nothing else shows up, use worker to pop hut before we get a defensive unit (will cost a couple turns of work, but no big loss as we can't mine or irrigate yet anyway). With so much food, will lean toward building regular over hardy settlers.
Any other thoughts?
