Hard to say without minimap but...
3 is nice with GH+gems+cow but hard to work with all mountains and forest. Were we ind. it could have been right but now...could be good if we move sett. N and there's som bg NE.
2 looks like down south and have GH and wheat, yummy. Could be nice to start with our backs clean
1 looks fine and do i spot plains E? Ivory or wines maybe? Few worker turns to improve.
My vote goes to 2 and 1 in that order but all three are fine.
I don't understand how we could waste GH. IIRC they pop goodies when within cult borders and they will soon be. Agree with Tatran about settling on poorest tile and absolutly not on food bonus (read it somwhere

)
Good work BJ, I'm
edit: About GW's I'm reluctant to build any at all since I'm slow at expansion allready, but if we do I think colossus is good and it last all the way to flight IIRC. GLib would also be nice to be able to test the zero science path. I've never managed to do that properly and could use the education on that. Lighthouse I've never built. I go with suicide galleys instead.
But isn't it a waste of the sci trait to build GL? We make cheap libs and may be leading in tech anyway, note "may be". You're right about not spoiling the GA so maybe we should skip those wonders all in all?
