Possible solution: subscribe for a limited time, like 3 months, plan which games to play, and you will see your true commitment level
I've played and finished some games in my last month of 6 months long subscription. I agree, it makes you drop games easily if you don't like them that much(like outer worlds, bloodstained, halo series, sea of thieves, phoenix point etc.). I rarerly drop games that i purchased, it feels like i'm throwing money out of the window. But that thought makes you play boring games till the end and creates a huge backlog so i don't know which way is good.
As a side note, i dropped FF 7 remake too, because it came from PS plus sub and i didn't like it that much.
