I for one would love to see Superworld revamped for the Big Golden Book. I have the old Superworld in hardcopy and it was a great game. I feel that Superworld has real potential for new life with the new core rulebook.
I'm still beavering away with my revamp on the Quickplay PDF I did for the City of Heroes, changing it into a full sourcebook. Trying to have the five power types available to characters, whilst fitting it into the City of Heroes world isn’t easy. So I agree with others in this post that it’s a bit of a challenge to make the five BRP powers fit together in one genre, and permit them to all have equal weight in their strengths.
I think that Mutations tend to get left behind a bit as they only come in minor and major categories. I have toyed with the idea of permitting Mutations to appear in five strengths, rather than just two: Minor, Major, Strong, Dominant, and Extreme. Or something to that effect, as a way of Mutations keeping track with the powers of others.
Anyway, if Superworld came back revamped in the modern BRP rulebook context, I'd certainly buy it.
