I'm trying to increase my rank at the end of the game, having all but demolished my opponents. Now my cities are building like crazy since it seems like buildings contribute to my final score. My question is, if I want a higher score, should I set most of my cities (the ones who don't benefit one way or another) to focus on Science or Gold? Do I try to get as many techs as possible before the game ends, or do I go for most $? Thanks in advance.
