Re: "Super Heroes" vs. "Superheroes"
It seems to me the main differentiating factors in the games I've played are the GMs weird obsessions.
Pix (posted as Big Willy on these boards) - Time travel, Cthulhu Mythos, the party gets split, PC deaths. These are pretty consistent across all of Pix's games whether he's running Champions, DnD or Call of Cthulhu. Pix has no Claremont-esque soap opera stuff. Games focus on superhero activity. The dice fall where the may in combat. Pix has always been pretty dodgy when it comes to challlenge level. These two factors contribute to the high PC death rate.
Al - Vampires, general dark stuff like Hell, seeming bad guys are revealed to be good after all, a long-term threat to blow up the Earth or universe, old people are better than young people. These are pretty consistent across all of Al's games whether he's running Golden Heroes, Amber or Vampire: the Masquerade. When he was running superhero, Al's primary source was actually Claremont era X-Men so there was some soap opera. And mutants. And people from alternate futures. Though not all that much, surprisingly. Al runs in a much more dramatic/controlling style than Pix does.
So no, I don't really recognise your types, Megaplayboy.
