Of course, true enlightenment comes only when you accept that you will never be able to play every game you already own, let go of the worldly desire to clear your backlog, and buy more games anyway. At this stage of enlightenment, you transcend the need for willpower.
Transcending the need for willpower is a great way to put it, regardless where you end up. It’s always good to dig into the basics of what you really want, what you get from it, etc.
Like in this case, if it brings you some small joy to spend $14 and get a handful of games you’ve been reading/hearing about for years, I bet that is objectively a good use of your money and time given your priorities in life. No need for willpower, because you’re doing the small thing that helps you enjoy life.
In my case, I still play games on PC and console, but I started completely ignoring the sales and mostly not even using my wish lists. I still occasionally buy games, and most often on sale, but between my existing library and all the other stuff in life I am happy just ignoring the sales. No need for willpower because the desire went away.
