I doubt it will be full on nudity and sex. It sounds to me like we're getting *something* but it will be limited, and I'm pretty sure they can't do anything that she doesn't give permission for. I'm not a huge Doja Cat fan, or at least I wasn't, so initially I wasn't stoked. But now she's kinda grown on me that I've been paying attention to her more, and I see why she's a good fit for the game, and I think this will be a pretty cool DLC.
It's pretty naïve to think that nobody will buy it though. The devs have mentioned themselves and have statistics that show that they have a pretty big audience who don't even bother with the explicit content DLC and they've sold well over a million copies to date. There's actually a pretty damn good game here, sex or not. Doja Cat is a huge name, and if she does something, anything sexual at all, it will pretty much be a first in gaming. The closest thing to it is Keanu in Cyberpunk, but he wasn't playing himself, and it was a mod that enabled him to have sex, and then they fixed it.
I look at it this way. Eek has provided a lot of great content to us already, and will continue to do so down the line. Maybe this new DLC won't be in line with the old content because they will obviously have limitations with which Doja Cat will be comfortable with, but it will still help the studio grow and create more content in the future, especially if this hits big. Eek is obviously not afraid to do adult content, so the more they succeed, the better produced content we will see from them.
I will be getting this DLC regardless of the content for those reasons. So what if this one is more funny than sexy? I don't need to jack off every time I load up a video game, and even if I do, this game has plenty of other content for that. I actually enjoy the game for its other content. If they manage to get away with actually having a sex scene with Doja, even better.
