I have seen someone criticize the writing for GTA DLCs and that it indicates how the writing for GTA VI will be. Not to mention I heard edgy jokes were removed from GTA V.
GTA VI will still sell somewhat well as the "fear-of-missing-out" will drive sales, just like nostalgia will. There are many people that are buying games, so even if 90% of gamers don't buy it, GTA will sell enough most likely.
Generally it doesn't matter though. Games that will sell are games that are fun. There are plenty surprise hits that are simply incredibly fun games. Palworld is a blast for example as are many others.
As an amateur NSFW developer myself it is best to focus on what you develop yourself. Do something you think will be fun, listen to criticism and assess it and then you will do fine. Your game is fun and I had fun playing it (though I am more of a fan of conscious corruption instead of hypnosis making the character not aware of it).
