Initially I was thinking it would be neat to have cages around the sides of the room where you could go pick a monster to display, interact with it, etc.. But there will also be spots next to each lady where you can select monsters. Having the cages then seems kinda redundant. Not to mention the complications (if monster is at location X then disable it from the list at location Y). So I guess I'll be getting rid of the cages. I want the owning of the monsters to feel more like befriending them (you know, like a Pokemon) anyway, rather than slavery / imprisonment.
I've been working on the Monster Club sell list a bit, adding a few monsters to purchase. I've also been working on portraits for a couple other girls for the brothel. This one's Sakina, a vampire. To prevent this from all being a little too daunting each girl will have their own partner type preference. Sakina here will prefer the undead and no other brothel girl will accept the undead.
All of the brothel girls are willing to have sex with normal men, but each will have their own regular guys. The difference between the monsters and the men will basically just be how you get them. The men you'll get through quests and jobs, while the monsters will primarily be gotten through the Monster Club (purchased with lots of gems).
I've had some other ideas like giving the girls fairy milk to restore their vaginal tightness, but that's probably unnecessary (and I should avoid too much feature creep).
Speaking of feature creep, after I get Nasira ready (all sex options with currently available monsters) then I should probably get back to fixing up The Abyss some more. Kendra's Palace still needs attention badly. I'm thinking of simplifying Yellow's events and making him one of the girl's regulars at the House of Pleasure. This probably means having him lose interest in Sienna a lot faster, and then have a few conditions where Sienna can invite him to meet one of the working girls.
