I totally like personalities beeing unique an differantiated from each other.
Still read through your post, tho i already knew i disagree with the idea of "changing personalities" or "mixed personalities". Becasue i think that would make them all too similar.
If a person(ality) is not your type - don't date them!
This is now easier due to the "Psychological Profiling" Upgrade you can archieve.
It's not about "changing" it's about "adding". As it stands, all the personalities are pretty one-note. Adding in nuance to how each character interacts with or doesn't willing interact with the feederism kink could go a long way to giving them depth.
See my example I gave concerning the bratty personality. That is the way I envision that specific personality type would engage with the kink if you, the player, were to get them into it via persuasion/them having an unrelated sexual awakening to the kink by accident/circumstance as they see themselves and/or the player getting larger.
You could even have that factor into the gameplay a bit, as perhaps different ladies of the same personality type could have differing reactions to their weight gain and/or the player's weight gain as it occurs. Some of them might not be into the kink at all and actively fight against it and disapprove, some might be SUPER into it in one way or another, and some might not be personally into it, but accepting and enabling the player's kink out of love, either getting fatter for the player or agreeing to be the player's personal feeder.
I find it personally delicious in feeding kink stories when the feeder character is low-key kinda not into it, but enabling the very much into it feedee character, for example.
Thus, say, the anxious personality, for example, would also have a completely different and unique way of interacting with the kink than the other personality types.
So on and so forth for all the personality types. I'm not suggesting for their personalities to be "changeable". I'm suggesting that MORE could be added to them.
I had a similar idea 💡 in spriit to your idea but it was more simplified in concept to what you are talking about I written in https://taylorapplebrook.itch.io/second-helpings/devlog/1306776/what-should-be-the-focus-of-major-content-update-4.
To summarize the idea 💡 centered around veteransy & the girls gaining a Veteran feede tag with the girl eating whatever you feed them like a base feeder persona & gain new dialogue with interactions. This would happen when one has the talk about Life-O-suction to reset their gains to do it all over again.
I like your idea MeeperMooper were different personas have some positive or negative interactions on top of their unique dialogue that you unlock with weight progression, I do feel from my understanding the game design that it would be more it's difficult to do then a verbial chickpoint that brings the change would be easier. Of course it will ultimately be up to the Dev.
Part of what you want to see is already there - differnt characters react differntly on the various kinks.
Some want to stay slim or even sporty some enjoy gaining and becoming more of themselves. Some are afraid about gaining - and yes some like it at first but then think it is too much or vice versa - so some girls are already going through different emotions and change their mind on the journey!
I think there is a lot of variety already there, and the developer is on a very good track to add even more personalities/characters in future!
I would not change the personality system at all, becasue it is beautiful as it is!
The game is about changing the characters bodies and then see how their mind reacts!
If you could convince every charcter to behave the same way that is simply boring because repeditive.
Not every character will be the right one for you but some character you dislike will be the right one for someone else! No need to even their behaviour out and kill variety in the process.
Ofc more personalities are better! But please do not messs with the already existing ones!
As it happens, I've been thinking of adding feeder & feedee versions of the base sixteen personalities. It's been a popular request (including, I think, one of the very first comments after release!) that I've never fulfilled. They would potentially start that way, or it might be possible (though tricky, perhaps involving some special upgrades) to convert a 'Bratty' girl to a 'Bratty Feeder' girl.
I plan to introduce some of them in the 'More Personalities' update, with a poll beforehand to do the most popular combinations first.
Okay, i lower my level of criticism here ...
Jumping between feedee-normal-feeder mindset might be what many ppl want.
Maybe i'm in the minority with ppl who want the personalities set in stone.
However:
If the "normal" personalities get their feedee/feeder versions then the current 4 feedees and 5 feeders should also get their "normal" version!
Actually some of the feeders are rly attractive, and i found myself wishing they where less perverted ie.: normal characters. Same for feedees.
Guess i slowly acquire a taste for personality changes (or sholudl i say mindf***).
Still thinking that it is a good idea to keep the good stuff as it is - just adding up to it.
Don't worry, I totally understand where you're coming from & I'll be careful if I add any such changes. It won't be something that happens out of the blue or accidentally. The player will need to work towards it via feeder upgrades, etc., and it'll be presented as the girl discovering the desires she didn't know she had or being corrupted into feedism through the player's actions. So any changes would hopefully be believable.
I'd love to add many more personalities in the future and versions of the feedists without the feedism might happen!
