I dun think Izzy will get boxed in, her path west should be wide open.
I like her resi density, Mansa looks rather poor there. He will have to race Roosy for the corn near Oasis.
Mao should be okay with some stuff east, but a fair bit of empty terrain as well.
Mehmed might send his free settler into a bad 2nd city like Dyes.
Peter will almost certainly have a weak 2nd city, but maybe he goes BW quickly..lots of copper around him.
Roosy has okay resis around him but could get into conflict with Peter fast.
Mao's diplo situation looks best, Peter naturally likes him and others are far away.
I wonder if this will be spotted by a majority of pickers, or if they will all go for Mansa
He also should get some food in his 2nd city, either deer + sheep or wheat.
Anything could happen, so i think taking Mansa has little value if 50%+ do so.
Mehmed always worth trying when surrounded by lush AIs.
Peter i think could end up in a pointless war cos Roosy has bfc copper.
Mehmed has no copper close so he will not rush in early, usually better for unit spammers to settle peacefully first.
