High to Low was designed for "Bored" Deity players. You know the ones that have it all figured out in 20 turns.

Tried High-to-Low just now so I could see what it was like...
Had barbarian world turned on so I could try and get some additional barbarian activity but nothing much happened (Continent got settled too quickly I suppose.)
I took a barb city with my scouting warrior as Portugual and got thrusted into Japan's control, and later took a city in a similar manner. Decided to be mean and declared war on two leaders a turn before it gave me control of the Iriquois (Who was researching
Writing without a single worker and only two warriors!!).
I did manage to pull myself out of the silliness he was taking part in, and had a lot of fun actually.
However... I did find it very strange and somewhat amusing to be declaring war on myself (In a sense) and then proceeding to eliminate my former empire via conquest
Back on the barbarian thing, I never did get to see anything from them, likely because the continent got settled so quickly, but a few off-shore landmasses did get a nice amount of barbarians settling on them. I dubbed one Barbarian Island because of the literal flood of units on it!
I'll have to try some more naval-oriented maps I suppose if I want to see more barbarian coastal activity... Although, I do remember playing on one of the earlier revisons... I think it was Fractured World or WorldGenerator, but the map was mostly land with some lakes and one-tile wide "rivers" scattered all over the place, and barbarians would still come with triremes and war galleys every few turns.
