This second paragraph doesn't make much sense to me. is present in FarmD for instance. It's not really all that groundbreaking of a feature... especially if that's all you can really point out as "exceptional". Like, that's sort of embarrassing no? And , this is just, such a weird thing to point out especially with how basic it is to implement. I would need to hear an elaboration on how it actually works in-game, but to me that just sounds like a basic Tongue Collides with Character part, add wet decal/texture or something. Again, something present in other games...
I'm still waiting for the list of VR games that have those features, it's easy to say "oh every game has that" or whatever but when you don't provide examples your point is lost. And no, it's not "embarassing" to implement small touches to make the experience more immersive, most VR games (and H-Games in general) don't have anything like that, you can call it "basic" but "basic" features are something most H-Games lack. Fair enough that FarmD has anthro x anthro but they don't advertise that anywhere, it's very telling that I'm learning about it for the first time from a random in a thread for a different game. FarmD is an ugly game with very low resolution textures, PS1 is an obvious exaggeration on my part it's closer to a cheap PS2 game visually and PS3 is an equally absurd comparison from you, The Last of Us is a PS3 game.
EDIT: I tried FarmD and it's completely behind Anthro Heat in every way, no dialogue, one map, limited poses, railroaded poses where you can't see anything besides the partner's face (unlike Heat where you can position in real time), lower visual quality, less customization and characters, less personality. Maybe all the good stuff is locked behind the dragon but I don't want to fuck anything non anthro, most people dont. It's very impressive for being developed by one person and I give them their flowers for the work but it is not at the same level.
Your one other example, Intimate, is an old, abandoned game that has barely any features, there's like 3 premade poses and no user interaction besides grabbing parts and moving characters around. I know because I've tried it recently.
It's moreso the fact the game offers barely anything to actually do. I never have any reason to launch it because well, there's nothing to do! Like geniunely. It barely counts as a game. The only experience I can imagine someone getting out of this, is someone who's a top and wants to use a fleshlight toy on inanimate dolls. That's about all this game offers, nothing more, and it's not even done all that well. It's just, so lacking. Especially for the $30 price tag.
Dude, it's a gooning game. You load it up and fuck/get fucked. It's not very complicated. It's very good at that.
As others have already said whenever H-Games (especially VR ones) try to implement some kind of progression or story it falls completely flat because the gameplay ends up being terrible and the actual sex part of the game is dogshit, that has been universally true for all VR H-Games. It would be awesome if more personality and story elements were put into Heat, I absolutely agree but getting the sex to be satisfying should always be the main priority.
I can think of two games (non-VR) that do it somewhat well and that's Carnal Instinct and Breeders of Nephelym however even those have mid gameplay and mid sex, this game has objectively better H despite lacking traditional gameplay elements and most people prefer good H over subpar gameplay implementation.
