I don't know if it became less enjoyable for me, necessarily, I still enjoy it just as much and am obviously more emotionally committed because of it, it just added a whole new dimension of pain(To be dramatic about it lol) that gave me some guilt from enjoying it(Especially from the sex scenes) and make me reflect on my own fetishes/preferences, as they were.
Yeahhhhh I got partway through AL and the scene where you pick(I believe Reina) up from her situation gave me such a bad vibe I didn't want to finish it. Unlike this, which made the tragedy, while obviously terrible, more worthwhile overall with AL it seemed to throw it further off the rails than I could sense it was already getting. I read a few comments after that told me it got much, much worse in the following chapter so I feel secure in that decision lol. Shame because it was a good game beforehand and BADIK is a top 10 hands down.
In the interest of paying it forward a similarly dark surprise(Not exactly a surprise) awaits you in
if you haven't played that. There are others but they don't come to mind right away.
