This is actually a good thing imho, the more it can captures mainstream attention the more it'd also attracts actual professional game developers & publishers to think that porn games has very high demands but low supply and give making porn games a try.
The problems i keep encountering with all the good games i watched here is either they're abandoned, in a feature creep hell, just scam, or not handled by professional dev (some were even solo yolo indie dev). They oftentimes got the good ideas but none of the competence or pragmatic drive of a real game devs.
Not necessarily. There's zero push to "jump" into the adult market now based on a game brigaded deliberately by 4chan. Some middle level publishers >MIGHT< be more open to a "naughty" game, this is not any kind of sea change of any type or magnitude.
The main issue is the deliberate brigading, and the fact you're paying 30 dollars for what is ostensibly a $12 game in the best of lights, nevermind the "misperception" about "interactive" sex.
At current time this game is a 3.99 shmup and a 3.99 tile tactical and thus contains $22??? sex scenes roughly 14 seconds in length with zero interactivity except for "premium" scenes where you literally click a button. Contrast this against any content you can find online from any SFM/Blender/Maya creator much less someone pushing the technical AND content envelope like HydraFX Bewyx or Pewposterous and it doesn't present anything positive other than "hey publishers/devs, get controversial and snippy on social media, and you can oversell any r18/ao by triple the expected margins".
This also isn't SF's even fifth foray into controversy and "misunderstood expectations". Sure the average steam user has no idea whom these people are, and are likely thinking "hey mass effect lite with snogging, yay", but I'm not sure how you exactly translate that into "adult games are totally kosher and kool now", when no such animal exists.
If this had been a fantasy game instead of scifi, the sales results probably would have been far far different due to the amount of adult games coming out in this particular genre.
You're also completely skating over the fact the game sections of this game were outsourced.
