## Description:

ArchipelagoSea is a very "special" map with the extreme amount of tiny
islands, and the map maker said "could there be a way to make
Archipelago Sea have 5M or 25M starters more often? I feel like the map
is too unorthodox to be played in normal settings"

So lets restrict it to the special rotation, like arcade maps. People
expect crazy-stupid games there.
