Well, siege warfare was not widely used until toward the end of the Peloponnesian War, so let's make a "Siege Tactics" tech, but make the siege weapons unavailable to Sparta, as they never adopted it...Hmm...Well, that doesn't help that much for specific tech trees...Well, Wonders:
Great Theatre
Oracle of Dodona
Oracle of Delphi
Statue of Zeus
Olympic Games
Spartan Military Code or Agoge
Parthenon (bye bye Temple of Athena)
Long Walls of Piraeus
*Erechthleum (courtesy of Greek-Stud to replace Acropolis)
Mines of Amphipolis
Marble Quarries of Thasos
Great Port of Byzantium
Delian Treasury
Great Harbor
*Spartan Defense
*Council of Ephors or Great Rhetra
*Isthmian Ship Track (Maybe a better name)
Persian Alliance
Now we need to name the techs appropriate to these wonders... Persian Alliance should be in a kind of "Persian Intervention" or "Persian Funding" tech...
Anyways, just my $0.02...
P.S. Isn't my Rockin' Kitty Avatar cool?

P.P.S. Xen makes a point. Let's put a "Mobilization" tech just 1 tech after "Beginning of Peloponnesian War", and that'll allow for Spartaite.
