I do not remember OCCC for Deity SG won. I recall only Demigod, Ottomans, small Pangaea.
They had good map but our was lot better. I never met before from Random(!) map 3 lux on individual island, monopoly on Ivory, River, and 3 Cows.

However, the fact that we got it without researching MMking ourselves was a stroke of luck. Power of our "style" was that after razing Cities AI gave more techs and gold for any peace treaty, it was good bonus at the end of the game.
Second "bottelneck" was GP - saltpeter. Again, only Zulu really had Musketeers, and we manage to finish them before it was too late. We also manage to control our Island, with a short eventsof Americans there.
I think on Sid those barriers could be too high and we could loose at some stage.
If speak about artificial map all possible, however, on "naturally looking map" I may think about similar map but a standard or large size, to prevent AI's talk to each other before Astronomy, say.
