I do that too with pretty much any VN that updates every 6 months or longer. Mostly because unless it was impactful, I forget almost everything about the VN. With BADIK, I've replayed it so many times that I've forgotten the details but as soon as I start replaying it I have this weird "Eureka" moment and go "I remember everything now."
I've kind of already been trying to replay from S1 ever since maybe March. I've been meaning to redo my saves so my choices are more "organized" but it's just so fucking tedious to do it all over again. And to add to that, I still haven't done the Ep 9 playthrough for Bella's route. Plus depending on when Ep 10 drops, I might not even have the mind to play it as soon as it's updated anyway.
Minigames aren't too bad except for the English class one. Epitome of tedious. Free roams are what kill me. Ep 7's HOT Party was annoying, Ep 8's dorm party awakened an OCD I didn't know I had with all the different variables stuffed inside (and DPC's walkthrough that even he didn't feel like outlining everything for lol), and Ep 9 was soul-sucking.
Just kinda tired, busy, and becoming more indifferent towards VNs and BADIK. You just ... get too used to not playing anything because you're waiting for updates that it becomes the routine rather than the exception. Once an update comes out, you just go "Eh, I'd rather do whatever else I've been doing in my free time for the past 12 months." or "Ya, Imma just beat off and go to bed. Ain't nobody got energy for 2 hours of that shit".
