Any rework only happens after they reply. I don't think Ocean is thinking towards that, he's second guessed everything he can. The review is not in essence whether it can go on steam because other AVN's with lewds are already there, but whether or not it is able to be rated PEGI 16 or whether it needs to be adult. I honestly can't think of anything they wouldn't allow now it's been sanitised by Ocean, it's simply that the game is huge, and a reviewer has to check the dialogue as well I guess, looking for any adult concepts that go beyond the 16 rating. I don't think there is anything, but we'll see.
The automated check probably noticed DAZ models and boobs, so the reviewers probably have to check there's no genital shots hidden in the game anywhere - adult by association with all other DAZ modelled games maybe?
He'll still be able to release on Gog, Epic might also still release, their reviewers are their own.
Right now it is the waiting game.
