I love this game, and think for roleplaying purposes and sheer options, its better than many call the best in this genre..That being said, story content is definitely drying up. The time to create the final battle between the MC and Lilith should be a priority, THEN focus on POST GAME content to expand the lore, rather than dragging out the story, honestly it would be a good idea to open up modding even further to allow people to add:
Custom Scenarios (ex: slave training/breaking scenes, or Rose sneaking into your room afterhours)
Custom Maps and Areas (strip club with VIP room for boning strippers)
Special Encounters(a harpy who attacks you and if she beats you gives you a blowjob until you pass out and lose all your money and weapons)
There's six years of foundation that skilled modders/coders could make magic with!
