Unity - Completed - Sex Formula [v1.4] [MIGI STUDIO]

I am not a lover of these DIY porn games, but here it`s just so good. Can`t remember when i saw so much well produced porn in one game. And that don`t have so many lags as other 3D games on Unity or like UE. Dev definetely deserves 5 stars for his work.

Sex Formula is not a game, that's the starting point. There is basically no story, no choices and the user has nothing to do except change the views and lights in a rather poor sex simulation. We are light-years away from the customizations, choice of characters and settings of Koikatsu and similar. I admit I don't understand why this product exists but for me it is truly awful. Extremely boring and repetitive.

EN:
I tried it with my Meta Quest 3s, and honestly, I don't think it's worth playing in VR. In fact, it's probably a good game in "Desktop" mode.

The whole point of VR is to give you the ability to interact with the world as much as possible, which in this game is nonexistent. It's just animations, and on top of that, the POV camera glitches all the time. The external camera and the rest of the game aren't very smooth either.

So, for VR: 2/5.
For Desktop: (I haven't actually tried it, but I'm sure it's much better) 3/5.

ES:
Lo probe con mis Meta Quest 3s y realmente me parecio que no vale la pena jugarlo en RV. De hecho seguro es un buen juego en el modo "Desktop".

La idea con la RV brindarte la posibilidad de interactuar con el mundo lo maximo posible, cosa que en este juego en nulo.
Son solo animaciones en las que, ademas, se buguea todo el tiempo la camara POV. Y la camara exterior y el resto del juego tampoco es que vaya muy fluido.

Asi que, para RV: 2/5.
Para desktop: (realmente no lo probe, pero estoy seguro que mejora mucho) 3/5.

best game lately animations are top tier. I think animations are the most important thing in a game, sure the game doesn't have much story. But who goes to a game to fucking read a book right? Just wished there were more girls and updates. Excellent

Literally unplayable on my not so-low end pc: 4060 Ti + 9 5900x. Usual black flashing screen during gameplay with many minute-long stutters and loadings. Is it meant to be played on 5090? So sad, cuz the main gal seem kinda cute, although the game in a whole voiced terrible.

From a physics and 3d animation standpoint its one of the best H games you can possibly play right now. with the best X-ray vision i have seen. and very good fluid animation.

Everywhere else however the game is bare bones. There are barely any customization options except for a few outfits, only a couple of positions, and the story does not exist basically. pregnancy, while having a lot of potential, feels tacked on as well.

I still give it a 4 star rating for what it can become in the future if the dev starts filling in the holes. Currently i would say the game is a 3 star rating. Fun for an hour or 2 after which the content has dried up.

Technically speaking its just but another animation viewer but it has something new and special about that makes it interesting.

Story and progress
Nicely made cut sciences, and progression. You unlock by playing, first anal then possibility to precede without condom.
Story is pretty much cougar takes under her roof awkward mute guy to make her cum and eventually impregnate

X-ray
Best I've ever seen in any game here ever. Different animations depending on pose, if condom is on or off. Even you can see tummy if she's pregnant.

Time progression
Depending on the day of a month hottie will have different moods. Might be Ovulating, might be bleeding. She might be in bad mood because of this cycle that makes gameplay different for example she wont let you go straight to anal and you have to unlock it by pleasuring her first and etc. You can skip time Day week and month intervals to see the difference. Especially noticeable when you make her pregnant and see her tummy go big.

Voice acting
Its a Japanese game. Its a miracle that it has English voice at all. No reason to complain about it. Sure its not perfect but definitely more then ok.

Controls
Very unintuitive and was having much difficulties with vive controller because binding is for oculus controllers. But considering gameplay is super simple and game literally plays itself its not much of a hassle. The most difficult part is to walk. I still struggle with it massively but you don't need to do that a lot.

Great vr experience would definitely recommend. Works straight out of box. At least 2 hours to try every animation and gameplay element. Around 15 different outfits. Probably 40+ sex animations and 12 or more dancing animations if your into that. Some customizations like different hair styles and colours here and there

Game graphics are really good. Also the game performance is good, but the rest...
The voice actor of the woman is really good, but sometimes voice stops working. This is very annoying in the few story parts. Also there is not really a story. I wish there was more story or different models of the girl.
With some improvements, this could be a good game.
In this state, the game is a one time fap, delate and forget...

Gameplay is meh and wish it was longer, but nice game for a fap .+1 for Animations, hope better gameplay games will come with animations like this. All and all i have enjoyed it a lot. 5/5. Dev please make more and more games like this. I like it when animations are not vanilla

Not so much actions needs to be taken by the player, which is usually not something I would like for a game Basically just a CG player with a lot of scenes. But the heroine just SO GOD DAMN TO MY TASTE I don't think I have a reason to give an excellent rating for this.

Great for desktop, idrc about VR. Good animations, voice acting and customization. There are a few issues that hopefully get patched; such as hair being too bright, and the succubus decals covering the cross-section view (which is one of this game's best features, however the visibility of it is based on the camera's distance to it).

1080p is max resolution and the volume sliders tend to be more suggestions than anything. I have everything cranked way down since I have bigass klipsch speakers and despite having all of the volume at 5% the chick still screams loud enough it could be heard outside.

The game is good, graphics are acceptable, but it would be nice a higher resolution option. Function buttons are effectives but too intrusives, maybe we can a more clean buttons.
I hope see more upgrades for this good game

There isn't alot of gameplay - it's really a trainer sort of game.
But in terms of the actual lewd material - it's very well done and it's clearly bespoke, not ripping off DAZ or HS2 or whatever - so very impressive.

Honestly, I think it's superior to their previous games - Perfect Lover and Succubus Cafe - it takes some of the ideas and just makes it better. Multiple angles, internal view, preg etc...

The animations are great and I haven't seen 3d X-ray done as well anywhere else.

If you like x-ray, this is great

This game, in its current VR state, is complete trash.

As VR user, I expected a good interactive experience, but instead I got subpar optimization, no POV option and bad controls.

If you expected a Virt-A-Mate level experience, with POV, kissing, teasing, physics, and the girl Reika reacting to your actions, this is not it, this is just an animation player with a few 2D videos for the story.

The story isn't anything special either, so unless you're playing on desktop and don't care about immersion, stay away from this mess.

2/5 as this could be a decent desktop experience.

Excellent game with great visuals, beautiful animations, hot girl (with a bit of customization) and hands down the best x-ray and cross section I've ever seen in a game, like seriously which game lets you toggle between regular cross section and x-ray view that actually makes sense and is tied perfectly to the animation, down to the animation of guy cumming in a condom? Sure it's all preanimated, not a dynamic/physics based system, but it's better than not having it, and most games can't even do this right (there are few that do filling up of condom, you can check those titles in my ultimate sex sim recommendation thread).

Pros:
- graphics
- animations
- x-ray
- pregnancy
- girls appearance
- basic customization with outfits and color adjustment (clothes, hair, lips, eye shadows, eyes, skin, tan lines, nails)
- voice acting

Cons:
- bit buggy (can't talk to her after first birth, possibly buggy build, let's wait for update)
- pregnancy could be more detailed
- could use more animations and various other random interactions
- animations could use some variation as well (slight changes to position, penetration depth/etc)

Honestly if they make next game have multiple girls, with dating system, more detailed pregnancy system (condom sabotage/failures, birth control, non-consensual) and add bulges and inflation (maybe another succubus themed girl or monster girls) it will be the best game, trashing any garbage illusion made recently.

I think anyone that liked Milf Next Door - Saeko in the Room will love this game. This is basically the aforementioned story on steroids.

Very simple premise. There is a very short backstory for context and it doesn't waste much time before jumping right into the sex. There is a sex relationship development system with progression where you unlock slightly more positions/kinks as you make her orgasm more.

Visuals are decently smooth and respectable quality.
edit: You can't really adjust her body proportions and her hair color choices (too loud) aren't great but I was a pretty big fan of her default look.

Voice acting is very nice and has quite a bit of variety + triggers depending on her mood and her arousal during sex (she'll say different things depend on her Sex Drive - no drive, normal drive, hyper) as well as whether she's fertile or not and whether you have a condom or not. There are some inconsistencies in the triggers but overall it is good. Oolay Tiger does great on the English side.

Main concern is a bug where you can't talk to her after she gives birth the first time. Second concern is the game eats a lot of memory because the opening cutscene is a pretty high quality video. A lot of people will see a black screen because this game is very resource intensive.

OK, we're dealing with a masterclass here!

It's certainly not the best game you'll ever play, but it's certainly the best in its category of “real-time scene viewer” or whatever you want to call it.

Granted, the walk-around phase is pointless, but everything else is (almost) perfect!

The animations are top tier! Quite simply! Unfortunately, the lack of personalization is the price to pay, but it's worth it.

The “story”, if you can call it that, is nice and sexy. The female character is a real hottie who'd give a priest a hard-on!

As you progress through the story and unlock new positions, it's not just a message telling you “bravo, now you can put your willy in the poo-hole! “no, there's a whole set-up that's... wow!

In short, a game I can only recommend!

If the studio has plans to make new games, and if they continue on an upward curve, then this will surely be one of the best studios we'll ever have!

Translated with DeepL...

seriously, how can people not give 5 to this game? fun and well done, not so buggy, wish they could add more nasty things, so great potential! moreover, I can't explain how others can rate without any comments while I have to write 300 words..

Not bad, reminds me of an Illusion Company game. It sacrifices variety to have personalized scenes that give the feeling of the girlfriend experience. I know the game can get monotonous pretty quickly due to the lack of variety but playing it for the first time is quite enjoyable.

I took away one star because it's obviously an inferior version of an Illusion game, and another because they left an exploration mechanic that doesn't make sense which makes me understand that they left ideas discarded in the final version.
