Zardnaar, Greece and Maya deserve this, at least on the mid-levels.
The problem with Babylon is that in C3C , it simply is no longer the top culture civ (it undoubtly was before).
For a 20k game, you want a coastal start and an early tech lead (SGL chances). In other words, SEA or EXP.
That makes Byzantium the prime candidate; Spain, Russia and Arabs as runner-ups.
For 100k, growth is everything. And I really mean growth, not expansion (which always is important).
In C3C, you will whip (Feudalism!) all those Libraries and many Temples, and at least partially the unis and caths.
In other words, AGR (Celts and Sumeria).
Babylon deserves the 1st tier in the earlier versions for being the culture king.
But in C3C, several Civs outshine Babylon here - and what remains is a Civ with worthless starting techs and a horrible UU. And no killer trait.
