Out of all the bonus resources I notice that stone and copper are ones I want to get rid off UNLESS its on grasslands and I need the hammer yield OR it adds adjacency for Industrial Zone. Even in the second case since Aqueduct and Dam give more adjacency and often districts or strategics like coal and Iron (which you can't remove) Stone and Copper falls down in the priority scale. I wish they brought back stoneworks which used to give happiness and a gold! Instead can give an amenity and boost the stone. https://civilization.fandom.com/wiki/Stone_Works_(Civ5) As it is at most stone will be 4 hammers. Used to give +2 gold but gathering took that way. Since it messes with district placement or farm diamonds I often take it away. Honestly even without it a unique cultural improvement would just be better or a seaside resort or Moai. The mauseloum wonder in civ5 used to make stone amazing +2 gold! Now its not that anymore at all. Maybe Im holding on to a past mechanic. But I wish they made stone and copper better again - it feels weird they made this bonus luxury something to be stripped from the map. 2 food and 3 hammers I feel just don't cut it for good yields when that's just a basic mine. It should beat a basic mine. Maybe stone can give tourism later? Stonehenge being the real life example?
