Stone rocks!
Buffs the Stone resource: now grants +2 Production instead of +1 and it can also spawn on plains, plains hills, and desert hills, not just grasslands.
New Quarry model has also been added just for desert, without any out-of-place grass patches. Benefits not just the new Stone tiles in desert but Quartz as well, which has always been able to spawn in desert.
Building a quarry is no longer a chore to get the eureka but a viable alternative to harvesting, and tiles with stone can actually compete for being some of your most productive tiles in the early game.
