Yeah the penetration is absolute perfection. For me penetration physics are super important and Fallen Doll OL nails it down. The skin textures are also amazing. In fact I even bump up the resolution to 120% and zoom into scenes real close, nothing beats their quality, and their animations are really smooth. Just a couple of clipping issues that I want fixed, especially for the Dr Anya, she has lots of clipping issues in her scenes. But that's because I'm a perfectionist and want my scenes to look great.
Now as for Honey Select 2, the huge problem with that game is that it's also, like OL, meant for sex scenes, but it absolutely fails to impress me. It has no story, so you expect the sex scenes to turn you on. I get it, there are tons and tons of mods, but what's the point of it all if at the end there's major points that make the game incredibly subpar (I'll explain below). Don't get me wrong, if this was a 5~7GB game, I wouldn't be hard on it. But it's freaking 50Gb, and it does such a poor job for its size.
For your reading, 4 Major points that highly bothered me in HS2:
1) You know, the skin texture looks like crap. For 50GB they could of thrown a 2GB texture for all I care. I mean it's silly to have such bad textures for a large game. At least have something decent. I bumped everything up while having all the HQ modded skin textures, but still looks bad.
2) My god- the camera is absolutely terrible. I was getting a huge headache using it. I even put 2 hours of effort to get used to it, but no, it's so so so terrible, beyond words. OL's ease of use camera is a god sent compared to HS2. Camera use was frustrating during scenes, something that should NOT be a thing for these games.
3) I get it, the game is meant to be censored, maybe the scenes would of looked better censored even though I don't enjoy censored in the first place, I don't know. I still feel like it's a huge failure if even the mods can't save the game, to give us a decent looking penetration. I mean look at the pictures below. It's horrendous. Huge turn off.
4) The game is badly optimized. Like, very badly. I have an RTX 3080 and even for me the game is lagging and slowing down during scenes, to the point of affecting your enjoyment of the game. Also crashes, and crashes, for no reason. Something I never encounter with other games.
Summary: Overall for how big this game is, it's nothing but a huge disappointment for me. Just gotta honest. A game like Succubus Cafe is only 8GB and blows HS2 out of the park for how much better it looks, and how much better it runs. It even has great penetration in their scenes, and even better skin textures! Who would have thought.
