- On Reno with two supernatural Spheres, the ratio of mortal to supernatural is more or less 50-50.
- On Kingsmouth, which is a single sphere (vampire) game, it's 50-50. Additionally, on Kingsmouth most players only have one character, due to the strict alt rules, yet still half the characters are mortal.
- On The Reach it's more like 1/3 character is a mortal.
This was just me quickly pulling up census on those three games, the ones I'm online on ATM.
Edit: By mortal I mean plain mortal, mortal +, or mortal sub splats to the big scaries.
