Maybe, I missed it, but, what were the traits for the two leaders and the starting techs for the "Empire".
I spoke to a friend of mine, whose wife is native Hawaiian, and spent alot of time there.
He suggested Kamehameha as [EXP/SPI] with Fishing and Mysticism techs.
We also noticed that you chose the Aztec Jaguar Swordsman style, and not a Hawaiian Spearman (w/1st strike) or a Maori Pounamu "Swordsman".
I also might have thought Polynesia would have had a UU of an galley that could travel accross oceans (to reach other islands or continents).
With at least 3 different UU possibilities for the different islands, how can this one Empire not be 3 empires, maybe more?
This reminds me of the Native American situation.
Multiple tribes with their own unique traits and units, where, it would make since to have 2-3 different tribes.
I like the introduction of Polynesia into Civ4. It is definitely missing.
