Or, on the other end of the spectrum, you have something like A Zombie's Life (and its spiritual successor, Zombie's Retreat), where the game just completely collapsed as a narrative because it was written around the assumption of there being something at stake. But when he announced plans for an optional "hard" NTR mode that would add another male character into the mix, the game's community when into such an open revolt that he not only abandoned the idea completely, but also stripped out any scenes that would've involved the zombies (despite the game very specifically setting them up as a sexual threat as part of its worldbuilding) because he was so worried that it would cause another uproar. Just about the only two remnants are a single conversation in the prologue and a handful of "save the girl from being groped by a zombie!" CG illustrations as part of a minigame that merely lead to standard game over.
And unfortunately, the only thing left in the aftermath of that was a bland harem setup that felt like it completely forgot that it was supposed to exist in a zombie apocalypse because the creator didn't fill that void with anything other than stroking the player's ego. Some of the early scenes at least manage to maintain some kind of connection to the gameplay, but as you get deeper and deeper into the game, it devolves into such a low-effort power fantasy that the story loses all ability to even pretend that there's any sort of risk or dramatic tension.
