I just wish to dispel some myths.does anyone feel that the % longer GAs monopolies underperfoming?, it feels like the only civs that could really use them is brazil, persia and china. i have some ideas:
This is actually not true at all. the Artemis adds food equal to 10% of pre-consumption food while growth like the monopoly, or the tradition bonus or the rationalism bonus or the Chinese/Indian UA, adds % food post-consumption.a) increase the %, the increase is half wonder (chichen) while there is other monopolies like 20% growth (2x atermis).
This is actually a pretty big difference especially in bigger cities.
Let me make an example from my current game.
I have a 20 pop city that generates 20 food post-consumption, it being a 20 pop city means it consumes 40 food per turn, meaning the total food income of the city is 60 food per turn.
Artemis in this case would provide 60 * 0.1 = 6 extra food, while 20% growth would provide 20 * 0.2 = 4 extra food.
The main practical difference here is that %food(like ToA) increases the actual possible max population of the city while %growth only decreases the time it takes the city to reach its max population.
Also worth mentioning that ToA is an ancient era wonder and Chichen Itza is a renaissance era wonder.
