I won’t start talking about the whole altitude thing, i’d like everyone who feel included in this thread to post their reason(s).
In my case, it’s because CtoSG is the only playfield in the secret world which isn’t very respectful of the first keyword of the game : Secret.
I mean by that : most of the time you can pretend not knowing what’s around you, be blissfully unaware of supernatural and occult things of the world, because of cities.
The Secret World is a running style meaning that a whole universe of myths and magic is hiding in dark corners, it’s mysteries we like to hunt and uncover. CtoSG isn’t hiding anything, it’s facesplashing mythology and djinns and stuff.
So it felt weird to me, for the first time, to completely swim in occult and be disconnected of that “masquerade” feeling or even the modern world theme. I think it’s what missed me in that zone.
So i agree with those saying the City of the Sun God is a hidden thing by itself, you’re landing in a secret territory buried in the ages. It felt different nonetheless and i prefer the style of investigating shadows rather than visiting MysticLand (and CtoSG doesn’t even remotely look like a city to me).
