Hi Rhye,
I've checked 2.62 and it's great! However, I have found some anomalies in RoC: first at all, marsh and jungle clearing are coming together: both of them are available (this isn't bothering me, but maybe you don't know this). Having such a large basic turn setting, it will let to clear marsh and jungle possible only on a few tiles, so basically the original idea of having large jungles will not be affected.
Another thing is that when you play the basic game, depending on world map size and number of civilizations, sooner or later any piece of land will belong to one of rival civilizations, and then (at the latest) wars will begin for the already occupied land. In RoC this is not going to happen, because there is always some land (till navigation in Eurasia, Africa and Oceania), later in Americas and Australia, so basically that moment of every settleable land is belonging to someone is never arive. And because of this, there are too few wars. In my games Australia, for ex had a plenty of free, settleable land even in modern times.
Maybe you should try to fine-tune a bit settler costs, or make food/shields production boost even more for european civilizations in the beginning of industrial era, or anything else that can help them to ocuppy all free land till the end of industrial era, at the latest.
