I've been working on a blend of the two that, in addition to just
being a blend of the two, is "professionless", in other words the player chooses the spread of favored/non-favored categories rather than having them dictated by choice of profession. I have been seriously considering leaving all 13 categories on the same character sheet, and having the "default" spread be 5 favored (cost 2 DPs), 5 non-favored (cost 4 DPs), 3
restricted (cost either 6 or 8 DPs, I haven't decided which). That way I can have the players aboard the space station when the catastrophe occurs, the players in the post-apocalyptic scenario a few years later, and the "wizards" thousands of years later still,
all using the same game mechanics. Then again, this setting also assumes that "psionics" bears roughly the same relationship to "magic" that chainsaw sculpture bears to bonsai, so "mystical arts" is every bit as much a group of intense specializations as, say, engineering. It doesn't seem unreasonable to me to say that with categories requiring as intense a focus as Combat, Scientific and Mystical Arts, if you focus on
anything enough to be competent, there's going to be
something else you seriously suck at.
The forum I linked to above is one I check often (of course), so feel free to check in now and then and see if/how it's working. I'm not too proud to admit when an idea explodes in my face, especially if it means the person I admit it to may have a better idea to make it non-explosive.
