In most cases I would agree: the interest of a story, in adult games just like in any other field, is that it comes from a story teller who has something to say to the outside world, and the reader/player must let himself be guided by them. However, in the particular case of EK, the very specific interest of GGGB which made it unique was that the labyrinth of choices and options was so vast that it let the players create their own story. I am not a porn game connoisseur and ORS is the only game I really play, but from the few other ones I have looked at EK seems very unique on this. And one could argue that she loses this specificity with ORS, as she deliberately closes some paths and options for the player. To me the ultimate example is the threesome Lena/Louise/Ian: you cannot have it unless Lena has cheated on Ian with Louise. I mean, how absurd is this ? Why would faithful Lena not be interested in experimenting with her serious boyfriend without cheating on him ? This is the sort of constrains EK brings to her game which make the whole thing particularly annoying.
