It will take way too long to go through all the possible reasons for the problem, but I think you’re making your Mus Guild too soon. When a GMus is born, it is given 10x the current tourism of your empire and that number doesn’t change, so later GMus are much, much more powerful than earlier ones. Yes, in some instances it may be more beneficial to get a couple for Broadway, but most of the time not, imo.
This all assumes that you didn’t use Sacred Sites, which is prob the best choice on a Tiny land map on King.
What turn are you making 62 tour? Is that base tour or with boosts? How much culture does Mor have currently?
