If the Creator is listening I have some suggestions(these don't go in any order)
1. A lovense system, to connect whatever you're using to the scenes of the game to match rhythm and motion of the scene.
2. Encampment Bosses that provide a better challenge and loot with unique loot.
3. Capture events that happen if you’ve been beaten in an encampment like being sold as a slave, kept in the camp and kept as a breeder, relies on a collar that makes you weaker once removed you can escape.
4. Slave capture, knock out an enemy and transport them to your camp and reduce their willpower to send them on expeditions to gather resources and money. Willpower affects the likelihood of escape and the efficiency of gathering.
5. Boss capture, Capture a boss after beating them and enslave them, break down their willpower and assign them to the only thing they know and profit from it.
6.Enhanced pregnancy, A wait period before you know your pregnant builds on suspense and wonder, So instead of it being you know right after the scene it's more like” I wonder if I'll get pregnant?” with High fertility it's more like “Gods I know I'll get pregnant from this!” also an internal view that plays
7. Motherly instinct, After your child is born you can visit them in the nursery and play with them, interact with them just be there buy them toys to play with. Maybe even nurse them like a mother would.
8. Jobs, Making money besides looting by working at a bar serving drinks watch out for drunk patrons, working at the nursery some males are looking for a hot thing to breed like you, Take a job at the ranch managing the centaurs and keep an eye out for the feisty ones.
9.Round 2, After a scene continue on for longer, you can go however long depending on you carnal instinct level going longer grants more XP
10. Free cam and POV, get a better angle on the action or enjoy looking into the eyes of your lover.
I concur with many of these suggestions. As Carnal Instinct is supposed to be a kind of "sexy Skyrim", remember that actual Skyrim exists with Lovers Lab sex mods that get extremely elaborate and do things like this. It's not quite so easy making everything in UE5 as it is letting the nth version of Gamebryo practically automate away much of the pain, but it's worthwhile in the name of fun.
I'll respond to select points that are noteworthy.
To (3): It's a mechanic that can get strongly hardcore and glitchy depending on how it's implemented but the concept is fun. This implementation typically struggles with disallowing the player from unequipping the bondage gear and correctly managing the enslavement status. The game has a cap on save files which generates issues when systems like this break because the player would need to roll back to an earlier save unless a smart debug tool is available. I say the developer should fix their state management bugs right now --
as I mentioned earlier, the mismanaged pregnancy state effects are a sign of a lack of handling for states and stat changes.
To (6): This is a more stylistic change but doesn't sound so bad to implement and really adds a lot to the feel of the event. The game implementation is super lazy about it right now though -- when scenes abruptly end after a cumshot you just know the pregnancy chance procced a "successful pregnancy" even when your character is already pregnant. Typical early dev jank.
To (7): Ohhh boy. It's lovely so long as the player doesn't have enough babies to fill the entire province. That's the whole point to game mechanics like anonymous caregivers taking away your children -- they're built with expectation that the player will have way too many kids. It can be done by keeping an array of X recent children on file and talking to the stork to visit a random entry of the array. Not sure if they'll be removed from the array over time or if theoretically a game save with the last pregnancy being game-years away will always spawn a permanently frozen-aged child. There's jank around this kind of stuff.
To (8): It may as well be ready considering the taberna seems to lack a server. Note that a lot of these features are female-player oriented. I think it'd be funny to see a lounge-lizard cougar kind of woman prey on a male player character. The UE4 version had a few events (noted on the game's wiki) but it was always transactional instead of risky, like alternative ways to pay off crime bounty.
To (9): Carnal Instinct stat feels underutilized since it maxes quickly so this is a decent idea. On a relevant stats note, later weapons should have higher crit chance boosts because the Fate stat's crit boosts are weak to the point of useless and the Fate stat overlaps with Carnal Instinct stat too much since they both boost fertility and virility. Alternatively nerf crit multipliers and give Fate stat better crit chance boosts.
Related to crit stat efficacy, it's smart that the developers have blunt hammer weapons specialize in crit by having better crit chance and multiplier since their moveset is slower and more narrowly aimed. Though from what I've seen, the difference is still too minor to justify using blunt weapons. The developers seem afraid to give players too much crit chance, and what I've seen from various games over time is that crit mults shouldn't start at 2.0x because it's too high to easily balance crit chance availability around. The base mult should be closer to 1.5x, which lets the weapon stats have more variety and control balance better.
Heavy melee weapons are very interestingly balanced from the two-handed sword I got to use. Because melee damage is additively boosted by strength the weapon can't just focus on damage output because damage is arbitrary from this additive. So heavy weapons typically have movesets with longer reach and wider sweeps, which is smart. Although the 20% movement speed reduction from having a heavy melee weapon out seems too cruel, it's compensated by the fact that a shield worn on the player's back contributes its block stats when the player blocks with the melee weapon as if they blocked with their shield instead. It's a highly effective gameplay solution. The blunt version of this would probably have high crit chance and multiplier but a narrow and short aimed moveset.
