This will be a short post because I have some day job stuff to wrap up before going to bed, but I looked at Facade yesterday (see my write-up here), and it's a Resistance toolbox game and therefore somewhat similar to Hwaet.
In short, one of the things that I'm thinking of doing with Hwaet is moving away from a system that's basically a simple reskin of the system to a different one.
Basically, the idea is that epic heroes need to be flexible, and the role system I was working on doesn't work well for allowing people to really explore the spaces I want to go to (though, perhaps, elements of it could be retained in the form of domains of specialization).
What I'm thinking about doing is going to a larger dice pool size through the use of an additional layered mechanic and getting rid of roles in favor of a destiny system.
Basically, each destiny represents an affiliation with some sort of phenomenon, typically one that is cosmic in nature. At character creation, the PCs choose a few destinies, but progression throughout the game involves overcoming these phenomena.
Characters gain destinies based on the way in which they confront the challenges they face; a threat associated with war, for instance, would earn the destiny "Bringer of War" or "Peacemaker" or something like that depending on what the solution is.
Thoughts?
