Even this is ten times better than no context whatsoever. Watching animation loops is as far from playing a porn game as you can get. Even in Rance there's a lot of interesting scenes which involve backstory of girls, his characters and stuff like that. If you'd simply get an art of him fucking a random girl after you grinded enough points - nobody would praise those games.
Except the game does provide context for these things. Why the girls are mega horny, where the xenos they are fucking are coming from, why they are willing to fuck them, all gets explained. And Subverse is already confirmed to have multi-minute long scenes as rewards for completing loyalty quests. You're complaining that Subverse isn't showing things other games reserve for deep into the game, after you have built up a relationship with the characters and done their personal quest, right at the beginning before you have had a chance to do that in the game. Well no duh. That stuff comes later in the game when the plot has progressed enough for character development, and personal quests, to have had a chance to happen.
Subverse already tries to provide some context like with recruitment scenes and it works well despite scenes themselves seriously lacking (you just jump right into the animation, no dialogs, no undressing animation, almost no interactivity). What's laughable is how these barebone scenes are "premium" ones.
So like most porn games?
- Most dialog in porn scenes is them describing the sounds/movements/emotions of the characters, since most porn games use still images, or very basic 2-3 frame flash-like animation, and thus don't have the ability to fully depict all the range of motion/noises/facial expressions people expect from porn. You look at other fully 3d sex games like Wild Life, or Fallen Doll, or Illusion games, and there isn't much dialog in those because you don't need dialog to describe things you can actually see/hear in real time.
- Beyond that, sex scene dialog is usually "I love you! Fuck me harder!" cringe porn dialog most people complain about since thats already been established before they start having sex, and gets in the way of hearing them enjoying having sex via moaning, grunting, and hearing the wet slapping noises of them having sex/getting filled with cum. There is a reason why most SFM/Blender videos with VA work have little to no actual dialog, and its all just grunting... no one wants to hear them talk during sex, they just want to hear them have sex, and enjoy it. Hell, many of Drills3D's longer 15 minute videos have nothing but grunting and moaning noises because people don't want that.
- Undressing animations are also typically skipped in these games because most people don't care about, or want to see, people undressing. that is just wasted time before the sex starts. Just look at Japanese VNs. They typically just go from girl is fully clothed, to *rip noise*, then nude. Undressing scenes are typically reserved of sensual, romantic scenes, which is not what this is, or even markets itself as.
- The same thing with interactivity. You look at most porn games on this site, or most porn games in general, and there is literally zero interactivity with the sex scenes. There is the a still image, maybe some slight 2-3 frame animation, and then you can sit there looking at it until you get bored of it and hit space bar to continue. The only porn games with real interactivity during the porn are games like Fallen Doll, Wild Life, and Honey Select, which lack real gameplay/plot beyond making a girl and watching them have sex. And people complain about those kinds of games because you have to spend more time trying to get the camera into a good position, and deal with a bunch of intrusive menus to get the thing you want done to them, rather then just being able look at already precurated porn thats designed to show the best angle in the first place. And the amount of interactivity you get out of the premium scene is pretty much the same you can get out of the more advanced scenes in games like summertime saga, some speed options, and then a cum button.
So you are complaining they are not doing the things most other games don't do, because the game either has no reason to do them since its fully 3D, and/or because people complain about them getting in the way of the porn.
You don't even need to integrate the porn in the plot, just make optional side events. Like you completed a mission using Lily and she got horny. You get a new dialog with her, you talk about lewd stuff, maybe add some dialog options here and there and after that show an animation, even if that same loop from Pandora. Add some dialogs during the sex. Fill the game with these optional events and voila - Subverse suddenly became a much better porn game with actual interactions with girls and lewd content outside of simple animations. In Pandora you can just have two modes - replay the whole event and one is like currently - just the animation.
The game already does this with recruitment scenes, and this is how it will work with the loyalty quest scene. In fact what you just described is literally how the in-game interaction with Lily works as is. You talk to her, she mentions getting horny from battle, you do a ground mission, she comes back and mentions how horny she is, then you fuck her, and see the sex scene.
Besides that, porn games are often filled with context-less porn scenes because people are there to watch characters have sex. I can't count the number of RPG maker games where you can go into a city, and in some back alley find two random NPCs, who you will never see again, having sex, leading to a short scene of the character watching them have sex simply to give another sex scene in the game. There is no context or backstory behind who these characters are, or why they are fucking in public back alley, they just are. The same thing is true with Subverse. The girls are having sex with the xenos because they are horny and want to. Not everything is some big emotional moment that needs 10+ minutes of dialog preceding it. Some people just go "wanna bang?" and then bang. This happens even with main girls i nthese games. So many scenes where you can just walk around the main base, and run into them masturbating, or fucking a horse, for no contextual reason.
This also leads into the problem with, due to the wide array of fetishes the game covers, trying to make them part of side quests and such just leads to people running into scenes/events they didn't want to see. A common complaint of porngames, especially with ow abused the terms cucking, and NTR, have become. Imagine the rage from the anti "cuck" people if you could stumble upon a longer fleshed out scene of the girls fucking the xenos.
