Creating New City

Yea same. My second city is 36 seconds away from my main city.

Players makes branch citys next to one another is because they can defend against other player from taking over their sub (As dispatch troops distance is so near). And another point to note at high lv, alot of player city drop (meaning move city) next to you and attack u and wiped your troops. So if u build city close together your city and making no empty slots around, player cannot city drop against you. One last point to note is that u can spread your troops evenly at your city when u sleep (Lesser negative crops comsuption per city). Just something to add.
