I had to start a new account because my old e-mail no longer works, but I was playing a game last night and I realized that my friends and I tend to just grab wonders as they appear to make sure no one else grabs it. I found Atlantis but waited so I could research the techs that would not take long to get. I was nervous the entire time hoping no one else would come and grab it.
Before finding atlantis i "always" circle it, while researching all tech that takes 1-2 turns to develop.
When all tech than I can develop costs at least 3 turns, I will get at least 9 turns of science production, instead of the minimum 3 turns worth.
