If you like EP you ought to try the FPS game "Bioshock", which is a pretty good source for EP ideas. Basically, bioshock's plot has that a monomaniacal genius named andrew ryan decided he was tired of being constrained by the morality of the small and of being hit on by the so called "parasites", which seemed to be everyone who wasn't andrew ryan. So he used his vast wealth to construct an ultras libertarian city beneath the atlantic ocean called "rapture" (as in 'rapture of the deep") where he and like minded people would be free of petty morality, "parasites", etc. Well, things went for a while until a scientist made a discovery on the ocean floor that lead to unlimited ability to make genetic modifications in humans, called "splicing". Now people could literally buy super powers via genetic modification. Too bad that apparently too much splicing for too long seemed to lead to disfigurement, insanity and worse. You get dropped into rapture after your plane crashes in 1960, only to find out there are some things about yourself you didn't know. The plot and ideas from bioshock could fairly easily and painlessly be grafted into EP and might make a decent adventure or mini campaign where a habitat full of radical exhumans or something similar went down the path of rapture.
