SM:P is plenty generic. I run a homebrewed setting that is currently limited to Sol system. No animal races, though I have been tempted to use them as genetic slaves/assassins. Highly illegal slaves/assassins I might add. I have resisted temptation so far, but all that pre-made material is so very inviting.
Seeing ICE grow big and strong enough to write setting books would be most welcome and make me very, very happy. Maybe Pete could produce his Eastern Middle Earth stuff under a different name for RM? Terry is obviously taking a re-release of the Empire seriously. Considering how creative Defendi's work in SM:P was, maybe he could be tapped to write something?
Time will tell.
