Tips

     Tip:  Keep  a large money reserve while building Wonders, just in
case  you  have to finish a building in a hurry to beat other players.
Disbanding  units  in  the  city  that is building the Wonder can be a
last-minute boost toward completion.

     Tip: If you do not build the Great Library or its equivalent in a
modified  scenario,  be  very  careful about giving technology to your
friends  because  you will be giving it to the owner of the library as
well.

     Tip:   In   all   human   games,   don't   bother   building  the
diplomacy-affecting  Wonders  such  as the Great Wall or the Statue of
Liberty.
