I feel like there are some misunderstandings in this thread about what "a porn game" or "a game with porn" actually means. At first glance, I didn't even make any distinction between these phrases as they literally meant the same thing to me. At some point during the development, however, some people started emphasizing that Subverse was always MEANT to be a video game first, and an adult experience second, i.e. a "game with porn".
On the other hand, they think "a porn game" is your run-of-the-mill RPG Maker/2D sidescroller hentai game with static CGs and basic gameplay/visuals. That is, an adult experience first, game second...Well, what did you expect with the shoestring budgets these indie creators have? Of course they can't make a REAL game (TM) by themselves with just their monthly Patreon earnings of a few thousand USD at most.
I am certain the vast majority of backers expected Subverse to be an adult experience first, but with the added bonus of it feeling like an AA game with enjoyable gameplay and great visuals. I am tempted to make another poll about this silly discussion on semantics, but there has already been plenty of screenshot proof in previous pages that even the mods and devs have literally called it a "porn game" on Discord.
