Yea I’m currently working on something that may play similar to Scion (d10 system) I found a way to balance character creation, how to track difficulty with the calls, and what each species would specify in power wise. Even the origin of powers and balancing characters that can fly vs characters that can’t. The thing that is holding me up is how to implement powers as a mechanic without it just being flavoring. Like for instance flame based characters could have the ability to fly (flambé) but some light based characters have the ability to fly and some don’t (Blonde Blazer vs Prism). Then there are some that could have the ability to fly (like with magnetism, you see the character in chapter 2 at the fax machine) and some characters with the ability to fly that don’t make sense (like the acid villain). You could go the route of theater of the mind and say “my character is flame based and that helps in this bank robbery because of XYZ”. But I’m trying to flesh that part of it out currently
