I messed up :(
I finally started playing again, first time building on Cinis. I was so happy when this octagon fit like a glove (really, i fits perfectly, you cannot move it one tile to the lower left to the mountain or upper right to the river). Then i wanted to outline my collosseum space right in the center....but i cannot fit it, it always will be off center, regardless of building it straight or diagonal. Im so sad.
Now im thinking of making a huge recreational park with the odd support building and my villa in the center and moving the collosseum either to the island on the right or right behind the city at the top, leaving the island for the upcoming Circus Maximus (which i think will end up being the largest building we get by far). What do you think fits better?
Bonus question: Do you think this is enough housing for 50k pops on Cinis? Thats kinda my target. Its 588 residences at this moment.
