The lawmakers don't want you to live. Since there's pandemic going on (mostly bit settled down now but who knows). Lockdowns are forced, people are not allowed to go out of their house, how the fu*k they're going to live without huge savings & going & working out. No high hopes but there's possibility that you can make good living money from this, if fortune favours.
The main fascinating situation is that the transmission of porn is done by huge number of people in social media groups. But government is not taking action against them. But if you're earning money from it then government might be interested in putting you behind the jail.
I think here SFW means lots of teasing, nudity (not sure) is accepted. Only sexual activity involving genitals need to be strictly avoid.
People will stay with you if the story is really good. So In this case NSFW not should be the main focus or game should contain lots of lewds.
You can make indirect renders like what is shown in movies, they hide just genitals rest actions are seen. Like you can create renders of lewd scenes, just need to learn the technique how lewd is shown in movies for the sfw part.
Need to figure out technique about circulating the NSFW patch.
But if you're main focus was creating a porn game highly focused on lewds as a selling point. So that's not gonna happen.
I think for now the option is divide the game in 2 parts. SFW & NSFW. You solely need to focus on story & game mechanics rather than lewds. So on patreon just make it as SFW game and not an adult creator. Never ever tell anybody that you're creating an adult game. You can prepare NSFW patch which will add to the story as mod or extra content to make it more realistic. So do the coding in such a way that NSFW patch won't work without the sfw game which should be a core. On f95 you can share the NSFW patch. But don't say that I'm creating this or that in open public. Only say this is some sort of novel game that's it.
So whenever suppose the checking will come (which is never gonna happen in near future). You can say this is completely sfw game and based on relations or something like that based on your story. And you can say about the lewds is that this were unofficial mods created by other creators and you don't know anything about them or any relation with this.
