Challenge: Win Science Victory with Japan using only your starting city, Imperialism Settler, and any Capital you end up being forced to conquer. Raze everything else and just harvest experience to funnel it into your capital with minimal Culture/Science costs from low # of cities.
Just a fun idea I had.
I think the toughest part of that would be the low unit cap from so few cities. Would maybe need to grab Terracotta/Great Wall/Himeji to try to help.
