I think this is kind of a trend with Archipelago. Anyways I haven't played one of these in ages so I decided to fire one up as Roosevelt. Immortal/NH/NE as usual. He's not a Fin leader which feels too easy but Ind could be useful for building wonders and Org is a nice all-around trait. Anyways... I'm actually somehow on the way to winning the map thanks in part to GLH and Colossus which kept my economy roaring but it's incredibly unbalanced.
I'm sharing an island that fits 8 cities with Mehmed. And the only reason I could settle 5 cities is because I settled my second city aggressively right next to him. The island has one source of Horses near his capital and no metals. Only two other island chains are reachable by galleys. One is snow-bound and basically devoid of resources and on the other side is Ghengis with a nice capital but all other cities tundra. Far up in the snow, there is one site that has Iron and I had to settle it. Otherwise no metal. No Stone or Marble anywhere and just one happy resource with Calendar which is Spices. Meanwhile Hannibal has a huge island all to himself with room for 11 cities, has 3 happy resi, Iron of course and Stone. All good land too. Unlucky for him I'm beelining Fission and workshopped a couple of cities so he's gonna suffer!
The other AI's also got better starts but not as crazy as Hannibal. I conquered both Khan and pushed Mehmed off my island which gave me some more land to work with.
Anyways I learned what to expect from Archipelago:
1) It may be very unbalanced.
2) AI sucks at amphibious invasions and defending island chains. Warfare is easier.
3) Production is always a weaknesses so food heavy sites are essential to abuse Slavery.
