This is clearly cheat. If you can have fun while you ve been cheated its your business....but generally normal people dont enjoy being cheated you know...And it's TOTALLY AWESOME!
It's supposed to be fun, not balanced. A month ago y'all were whining about Gran Colombia. Apparently everyone got over it.
And I think the challenge can be overrated. The babylon gameplay loop isn't that complex... It's mostly about planning ahead.
Gilgamesh's science output is literally 5 times yours, I literally have never seen an AI this far ahead even on Deity. Even Babylon has more science per turn than you and they have a 50% penalty. Whichever difficulty this is, you need to dial it down a couple notches. If you get crushed this hard by the same AIs that have been the target of ridicule for 4 years, I don't think the problem is whether Babylon is in your game or not.
I think Babylon is a lot harder to play then some people want to admit. I'm not denying that the very best players who have mastered every system in the game can get some ridiculous results with them... but I don't think the civ was really designed with those players in mind, either.
For most players I think keeping ahead in science as the game progresses becomes pretty tricky. Some Eurekas are hard to achieve and not likely to be accomplished by the average player, and many Eurekas only get harder as the eras progess. So yeah, Babylon will probably jump out to a huge lead early on but staying there as the game continues is a whole different can of worms... one most players will have their hands full with, IMO.
