Hm...well here's my take: I liked polyhedron because I thought it was cool...the same reason I buy your magazine to begin with. The first four or five mini games were great: Omega world, Pulp fiction (aka: sky captain and the world of tomorrow)and spell jammer were some of my favorites. Not that I ever RAN those settings, or even read them all the way through. But it was very cool, creative thinking. The kind of thinking that I and other gamers enjoy this hobby for. And maybe it may not have been run so much as imitated in normal D&D settings.
I understand market pressures must certainly drive your publishing decisions because at the end of the day you guys are there to make money, not good friends. But maybe in your office, you could start a Polyhedron bulletin board, not online, but like a real bulletin board (boy, you can tell i'm old now) and tag stuff up there that might be cool. Then when you end up with a real whiz bang, develop it.
You never can tell, it could be the next spycraft, which would be cool if you did too....
