Okay. Leader choices:
Roosevelt: (Org / Ind)
Pros:
Organized helps keep upkeep down
Organized helps get courthouses and lighthouses faster
Along with this, Industrious calls out for GLH!
Good starting techs (Fishing / Agriculture)
Cons:
We are going to work water tiles eventually. No financial is a con here.
UU is lategame, past the really decisive moment.
UB is lategame, past the really decisive moment.
Very sparse synergy between traits and uniques
