Borrowing from MooingCat’s work Leo has developed his own spreadsheet to evaluate all special buildings with newer bonuses added such as blue GBG, QI and a few other things tweaked. Top 20 are below for anyone who is curious (does not include St Patricks and perhaps the latest GBG building) Correct as of 23/2/2025
