Re: what gives your pulp its pep?
(Near) continuous action , but also a big plus for me is exotic locations, and interesting situations. When I finally get my globetrotting pulp campaign going, that is what I will be emphasizing.
Also, with the pulp heroes, there was a sense that they were still basically human, not superhuman. You could believe that that sort of heroism could in theory actually be possible in the real world. Probably not in reality, but you don't have to suspend too much disbelief.
I've been known to play in superhero campaigns, but I always take my disbelief, fold it up nicely and put it on a shelf out of the way, before I play.
