I disagree, I had 3 games playing with that strategy and
and they all ended up with Algae, on my 4rth game I still
have not gotten farming 1 and have gotten crops, and no
algae in my water.
So I say building, exploration, science, then culture and medicine.
If you get in a crunch for food put all your villagers
on the crops as soon as they come up until the are
depleted and wait till they regrow and do it again!
That way all your villagers have farming skills building too.
