I am not a programer, just a free user,but I can tell something,maybe usefull.
(Sorry for the long post and lack of english knowledge)
Yeah, there are a lot BB games, we know,they did not made far, and almost the same.
Same, because the recipe is good, but not perfect, it has potencial, but come on...
The first game came out when this was a huge thing, now days porn games,good porn games are common.
(With good story, scenes, mechanic,etc )
If you realy want to "remake" or "rethink", keep the core elements, inprove the lacking parts, modify the disliked,etc.
And there should be more interesting elements in the game nowdays, not just "a novel" game with "some interactions".
For example, the game "Lust Age" got my attention because of one mechanic what I did not was in a lot of games.
When you change a dress for a girl, SHE KEEPS IT !
Not just when you are doing lewd scenes, when you walk into her on the street, she wears it, and doing the animations in it !
Or even in "Harem Hotels" they "using them" and makes the game "living". (ofc,these games are awesome, just mentioned one element)
Or in "Glassix"
Not a big thing, a small one, but a lot of small things can make a project game and succes !
Sure, you can make one big thing, like EA doing, they do big things, but lack of "passion, and care".
So just a few tips, wich are "small" in content, but can get a much more "life" into game (interact with the world, not just see the world)
-Dress variants for them (even if in the same animations) could do the color into the game.
-Mood system,and their dialogs and acting (animations) depending on those ( bored-just naping on the sofa,exited-dancing/jumping in front of it,sad-reading or facing into the pillow,etc-etc)
-The more girls is good, but if they feels the same and with "nothing different to offer than the others, what is the point" ?
(Different personalities are good, but physical differenties are another level, even if they are both used)
-If we stucked in one house for the entire game, it should be fun, to have many interaction, just just "event triggering".
Minigames are cool stufs too, but it they are optimals , so everyone could be happy.
-More places in our home, more interactions, more events,even if those are just a small one with 1-2 frames and lines.
(If those works just "spawn", they are worthless)
-That is good to have "fixed" event in fixed time periods, that a great way to plan your "life", but random events could make it has life, it's breathing,not just "reading" the story. So random events, even if they are in fixed places,but random,who is there, what what happened (not always the same person stuck into the washing mashine, washing dishes and got wet,fall into the pool,etc-etc
-Grinding is good, but it it's not much and do not "make an instant stop" for peoples.
It have it charm, we "actualy" working for fun (maybe the best if the game offers "sandbox/story, and just story telling") so gamers and fappers or both like myself could enjoy how it pleases us more.
-I hated Eric's character, but without him, the game would be borring, because he was the "source" of the fear, to lose someone or everyone ! I had to stop him ! But still, hated him xD
If he will get into the game, the mechanic againts him would be nice to have "dificulty levels" to counter him.
or anything what will make this game "hard".
-Oh and not a game related thing.
What will you do, what do you want ?
-A game from your ideas and share it with others, even if not everyone like it, but it's your?
(Negative feedbacks will less affect your work)
-Maybe you want just the core, and expand it by others ideas,preferences,etc ?
(Feedbacks will affect your work, good or bad ways)
Or mixed these two ?
(Personaly, I recommend this, when "everyone bend their expectations", so everyone can get good and bad things)
So far,just these are in my mind, and ofc, i am not a programer, so maybe they are small's in our view, but quite hard work or alone inposible to do so.
I loved the "basic concept of BB", and still but the very core game was good 15 years ago, nowdays it's not enought to catch our attention, not even to support, to let it sink again, and again....
Many uniqe games went into the abis (Breeding seasons,Simbro,pandorum), yeah, I was a patreon for them and for more games for many years,when I was younger and have money, but I lost my trust, so I just buy complete games personaly.
These words was not for offense,these are just my toughts.
I wish you and for every creators (uniqe ideas,remakes,reworks,expansions,etc) a good luck !
