This start does look tasty -- plenty of food, hammers from the hills, rare silver for happiness, and lots of riverside grasslands for cottaging. No forests for quick hammers, but you can't have everything.
I like the Sumerian UU, and the UB is fantastic. No city razing will be trouble -- AI city placement is too often just a little off ideal. Combined with flips after conquest...hmmm. Military strategy is going to require adjustment. Our creative trait will help a bit, though, with immediate culture and cheap libraries and theaters.
I'll check the eastern hill with the warrior, but unless there is something amazing to be seen settling in place seems right. Worker first build, research AH for the pigs and to reveal horses (if we are really lucky), mining for silver and the path to bronze working.
If neither horses nor copper is available -- a strong possibility -- then a quick push to Iron Working is probably needed. We'll need to chop jungle early anyway. But if aggressive nearby neighbors have appeared, might have to fall back and grab Archery for protective defense.
I'll have to generate a few rainforest maps to get familiar with what we'll be facing.
