actually, i was thinking, maybe you could add rarity settings like in some gacha games?
It's just, i think, i enjoyed this not just for the freedom of choice, but rather for farming also, seems pretty cool to collect bunch of slaves and guests with appearance of 100 and several traits.
So, i was thinking, since farming is kind of essential part of the game, why not add something that might look rewarding to the player?
Like star system, for example 5 star characters would have 4 traits, 5 skill slots(like maximum number of skills this character can learn, since skill learning is added), beauty score of 90-100, with starting 2 skills for example, and you know make them have of low chance of appearance in the wild, like higher cost in slave house, etc(like different methods of increasing their rarity)
4 stars a bit lower and the same for 3, 2,1, i mean can be adjusted as you see fit
heck you can even make 5 star to 90-99, and add especial rarity 6 stars with 100 appearance, i think it would highlight rarity stunning better.
Lastly, ofc it's just a suggestion, if you like it you could try it adjusting how you like, if not, then whatever :/
P.S., from different rarity systems, i think numbers with stars looks better, bc letters system (SR, SSR) looks to damn japanese, which would look weird as fuck in the western apocalypse with real life image usage
