That they are enslaved does not mean the end of their route (at least i assume so).
Many events that are available in "normal" form are not available in Slave form, so at least until we get those i won't consider those arcs completed.
And also... Just to end a arc/story at "she is a slave now, it's done" it rather cheap and dumb.
Most people would like to see at least a couple more events/chapters after that to see how it all works out.
Otherwise, what's the point ?
Development for Sister and Mother and Megan has gone into the next stage/chapter with being a slave.... That's my thought and opinion about it at least.
I disagree, for the most part. I think the enslavement scene is the culmination to their arcs and therefore the end of their routes, with the post-enslavement scenes essentially functioning as an epilogue or "post-route" content. It's not entering a new stage, it's over. They can't be corrupted further, even the options to give them potions and whatnot disappears. I agree it would be nice if he did a slave version of every action the girl can do normally, but sadly it doesn't seem that is the direction this is going. The slaves seem to get new actions, like Nicole and Jenny's show or Megan cleaning the house, but it doesn't seem like he will implement the Kiss/Titfuck/Handjob/Sex options again.
But whatever new actions they're getting isn't new developement, their developement is done and this is kinda like a reward for going through with the route (as they are repeatable actions and all).
I will play devil's advocate and point out that most games (and porn comics) with similar themes don't have much more after enslaving the girl, the scene where they go fully depraved caps it off. I do like the few that go the extra mile to give more on top of that, and I think having more actions for the slaves would be nice, but that doesn't mean their routes aren't mostly finished.
>And also... Just to end a arc/story at "she is a slave now, it's done" it rather cheap and dumb.
Not really, given that is what the game is about, it's the player's stated objective to corrupt and enslave the girls. What do you even want out of this game if not to enslave everyone? I don't think you can keep developing beyond "loyal and perverted sex slave" without ending up changing that status quo and denying what the game is about. Not for this kind of mind control-ish slavery, at least.
The problem with this would be if the girls all felt the same when they became slaves, but that isn't the case, so far. Jenny, Nicole and Megan had diferent focuses on their enslavement scene and in the few scenes they got as slaves.
The only thing I could see as a more conclusive ending to the routes would be pregnancy, but that would probably require the game to have an ending, which as discussed probably isn't the case with this, sadly.
