So the core is 8 by 26 or less, i left space for two more chruches when there are 5 gods. unlike the unworking youtube loops it's not calculated with maths, so use it as inspiration if you think you can improve it. the core idea is that leaving entertainment outside makes it reliant on all other roads outside the loop. putting the fun inside it makes entertainment stable. i saw people claim that the chess & beer club is unnecessary and it works city-wide, so you can try removing that, making the whole thing smaller. with rough terrain the outer loop can be cut into injection roads delivering goods and services from the other side. the surrounding area can be used to spam more churches to appease the gods, or if the location is rough to add more statues. i usually plop government mansions and giant temples there

so as i see it, my worker loop is smaller, self-sufficient, but flexible to adapt for bad terrains and insufficient space

just for inspiration

also can be easily converted into 3x3 loop, and into 4x4 with a lot of statues
