What if you don't want to "break" your slaves. I have no interest in having slaves with less than 0 willpower. Where does this leave a player like me. The bdsm side of the game has minimum attraction to me.I was thinking about this a bit more from the perspective of the new player experience and I think what might make the most sense would be to change the guest room to be tied into a quest to "break" your first slave. So initially the guest room doesn't even exist. You have your own bedroom and preferably a maximum of 1 open slot for a slave, who initially has to either sleep on the floor or in her master's bed.
So when you get your first slave, you get a quest to "break her in". I would suggest that for your first slave this just means getting her willpower to less than zero and getting her affection to loving. This unlocks your ability to build the guest room which allows your first slave a place to sleep other than the floor or her master's bed and also gives you a second slave slot. It might make sense to hint at a slave that would be easy to do this with like Amelia.
This also gives a continuation for that first quest. Your goal now is to train 2 slaves up to 60 in any skill (whatever skill you want). You could potentially cheese this requirement by just buying your first 2 slaves who already have 60 or more in something, but a newbie is more likely to just grab 2 of the first slaves they can get which will require training to get there. Once you've completed the training quest, you get access to the next guest room upgrade which gives you 2 more slave slots.
By now the newbie has the general idea what's involved in breaking and training slaves. Now you get your final continuation of this quest, which I would suggest should be some sort of bondage related goal to introduce the newbie to how that works. Not really sure what the best way to set that up would be, but completing that fully unlocks the guest room with all the currently available slave slots now available (plus preferably some extra benefits beyond just the slave slots we currently get for free).
It might make sense for the bondage class to include an actual tutorial bondage session where the game guides you through an effective bondage session with one of the willing slaves taking part in the bondage class.
What I like about this game is I'm not railroaded into a path. I can choose whatever direction I want to go, play however I want to play. I hope the game never goes in that forced direction.
Now there isn't anything wrong with your post, it is actually a good guide in many respects for a newbie who wants what you want. It just shouldn't be forced on a player.
Personally, I don't mind making mistakes learning a new game and if a new player over reaches or tries too much at the beginning and gets slammed...well, quit, start over and learn from your mistakes. This is very much a crpg in that regard.
