There is a game called
Empress Game where the whole premise is related to one scene in Chapter 1 of
Stray Incubus. Basically, if the whole ordeal of
Zycris being captured and dominated by female 'villains' was made into a whole chapter or game, then
Empress Game would be that chapter or game
. At least, it fits some of the main characters archetype ( of course, the plot and settings are totally different ). I'm not recommending it or anything ( especially since it is a sandbox game ), but just sharing the similarity, even if just one bit of it.
