I think the point is to get people who have "frequent nudity or sexual content," and "adult only sexual content" blocked on Steam to look at the game. Some people have those games hidden on Steam even though they're not necessarily against playing them (I'm one of those people). Maybe it will pay off and he'll make more sales than he otherwise would have, or maybe it will annoy people who thought they were going to get a different type of story. Time will tell.
Agreed, time will tell. F95 users are far from being mainstream. But if we use them as our litmus paper test for how a crowd reacts to a game starting out as one thing, and then becoming an entirely different thing, I think we will find that model does not work.
After reading the Patreon posts, Discord discussions, and some of the more "in the know" posts here on this forum, it appears more likely that he is doing it to avoid finding and paying for all new music. There are so many great games that have gone down the path of getting screwed over by changes in music contracts. First, it is insane that the contract supports and protects the artists without any form of redress for the client. Second, as long as devs continue to patronize these services and/or are unable or unwilling to fight them, this kind of treatment will continue.
The delay, stress, and money it cost Drifty was tremendous. His story is quite typical of what devs face on this issue. Does anyone know if Ocean received a warning from the muscian's licensing company or Steam, or is he being preemptive because of what other devs have faced? In the end, it is better now than after releasing much more of the season. Still unfortunate that he is going through the whole thing.
