I'll be blunt, the idea that gameplay is unimportant to adult games is absurd. Those that claim otherwise... Well, I'll leave this Chinese idiom here:
"You're like a frog at the bottom of a well".
I fully believe the adult game culture is forced due to necessity, rather than desire. The general gameplay elements we get are through annoying room clicker sandbox games, generic RPG maker games, or slave management. I'm not trying to trash any developers, there are some games in all three categories that I adore, but let's face it, we are kind of sick of the same gameplay elements over and over again.
The devs who make adult games are amateurs. Because of this, they tend to lean towards the writing and art aspect of the games and ignore the coding aspects. Meaning most focus on visual novels. Furthermore, the developers who have tried end up coding themselves into a corner, unorganized and not very happy with their work. Deciding instead of fixing it, it would be best to simply abandon the game, or start a new. Hell, even the developer of Mist, a very popular game right now, basically abandoned his old game in favor of a restart.
I have played far more adult games than I care to admit. For many of the visual novels, I walk away from feeling enjoyment or satisfaction from playing. I think "Huh, that was fun. Can't wait for the next release". Only to find myself completely forgetting the entire story by the time the next game is released, hell it's possible I even forget what the damn game is called. I have a word document filled with games I had to rate and give a summary for just so I can remember all of them. Chances are, similar things happen to everyone who replied to this thread.
Yet, the games I remember most fondly, some of which I haven't touched in years, I remember vividly. Corruption of Champions, Strive for Power, Free Cities, Lab Rats 2, etc. These games need no introduction to me, nor do they require me to spend x amount of time after playing them to type up a summary for myself. Some of these games do very well out in the wild, earning their developers a decent living.
F95 is the defecate location for adult games. It isn't Reddit, nor any message board, nor is it steam. The culture and opinions of this site are what sets the tone for the budding adult game industry, rather we admit it out loud or not. While this may be true, it only affects those of us who use this site and the developers who may want to research for their potential game. It does not speak for the rest of the world.
Furthermore, if you look at mods, how many people do you think purchased Sims 4 just to play Wicked Whims? That single mod makes more money than the vast majority of adult games, and it has been doing so for years now. You could argue that it is that popular because it is a mod for such an old and popular franchise, but at the same time, I argue that Sims 4 still makes money because of Wicked Whims and a handful of other mods. All the mod does is add new gameplay elements, no story and it barely enhances the art.
I will admit, there is a difference between a mod and a game. Yet, I feel my point remains valid. The popularity of Wicked Whims, which several major video game news sites have reported on, outshines that of any popular game here on f95. I think this alone shows that the potential market for adult games is much larger than we see stuck in our well, and that market wants gameplay elements.
Even if we look outside of the adult industry, to the larger non-adult games. Visual Novels are a joke to most gamers. Many of which would likely enjoy games that revolve around adult situations. That is a large untapped cash cow which games we find here on f95 are impeding the ability to tap into that market.
I would like to say that I'm not trying to bad mouth devs who make visual novels. Several of my favorite games are VNs. This issue isn't exactly their fault either. Nor am I blaming f95, as I mentioned earlier the culture is forced, not natural.
I fully believe that the only thing holding both VNs and games with gameplay back is balance. Most VNs have no gameplay at all, maybe a couple of mini-games or neat UI. While many games with gameplay have a very little story, and either poor art or in some cases none at all. If a game came around which could find a balance between the three things, that game has the potential to outshine any adult game or mod created up until now.
If the op is determined and has any skill at all, we should be supporting them rather than trying to convince them that they will fail. If they can at least create a bit of that balance I mentioned, they will most likely find great success.
