if we measure the content by playtime, there is plenty (15+ hours i'd say). if we talk about the content with MC's mom and sisters, well... most only works with the key ingredient of taboo, so it's a ymmv at this point. for me, the incest is implemented better than in any other game. anything is rushed, the immersion is great, the immorality of Bobby is never held back, sometimes he wins, sometimes things don't go his way so you are never sure what to expect, characters reacts in a plausible way to his fuckedupness, the corruption is very well done...
for me it is worth playing even if there is still a long way to go (at best is at 30% completion). especially because everything that works feels like the dev knows exactly what he is doing. that's rare imo
