I have news, new record post-patch.
Playing Babylon Science Victory turn 227.
Built Temple of Artemis T37 (after writing chopping forests), Hanging Gardens (T55, I beelined for it after writing), NC T65, Hagia Sophia T77 (founded religion, Fertility Rites, Tithe and Religious Community, later Sword to Ploshares and Relicary), Oracle T85 (For the GS points, Opened Patronage, with my next policy before Rationalism took Aesthetics and protected all non-mercantile CS), Tower of Pisa T130 , PT T140 with an Engineer from Pisa, T150 Sistine Chapel. Later once got Hermitage I built Kremlin and Brandenburg Gate for the GS points.
Opened Order for getting an Engineer with Faith for Hubble, later got Factory science bonus policy.
My tech Order was: Writing, Archery, Mining, Math, Philo, Theo, Civil Service, Education, Compass (Oxford Astronomy), Machinery, Printing Press, Acoustics (Stole Banking), Architecture, Economics, Scientific Theory, Industrial, Electricity, beelined to Plastics then to Rocketry and Satellites (without Chemistry nor Navigation), then Advanced Ballistics.
The last step is researching up to Computers and time Rationalism tree completion to get Robotics and Nanotech. All the upper part from Navigation was hard teched / completed with RAs / stolen (I stole only Navigation).
As you see my army was huge due to being permafriend with all Military CS from turn 100.
Babylon is the fastest Civ because GS points count 150% BEFORE other bonuses. That means that Oracle GS point is 1.5 + % modifier (with Pisa, Garden and National Epic 75% means 2.62 GS points. At the end I had +42 GS points per turn. I lost the count of how many GS I generated, I built my lab T180 and started bulbing them since then.
In the screenshot my culture rate is low because I sold Radio Tower and Museum to time Rati completion with Computers completion.
