I think preventing the “all other spheres must die” thing is on the staff to prevent but at the same time, you can’t hold to theme for some of the WoD (especially OWoD) spheres if they’re expected to be buddy buddy because some major magical aura is preventing it. (Mostly talking about Vampire - Werewolf here.) Ultimately “a ritual long before the start of game says no” is sort of lazy in my opinion.
As far as day zones / night zones go, I prefer that people just set the time of day / night when they set the scene, and adapt to whomever they’re playing with. Day zones / night zones, again, seem lazy to me.
The families thing that TR / FC had was cool because at least you had the whole “blood is thicker than water” thing which didn’t feel as arbitrary as “ancient NPC said no”.
At least in CWoD / NWoD, the whole “kill other spheres” is replaced with “we’re wary of other spheres, but we don’t try and kill them outright as long as they stay in their lanes” (with a few exceptions, like the Cheiron Group with their whole we chop up everybody else to make ourselves better).
I think I’m done rambling now.
