Thank you all so much for your input! As of now I'm planning on buying the Cabbage Hut and then after reading everyone's comments I might actually go for Cleo's Pyramid as well since I desperately need money for expanding. If I have any gems left over I'm considering getting the Royal Dark Unicorn.
Also one question, I have 1,250 crowns and have never bought any citizens from the Town Square. Is there any specific one I should most definitely buy or?
