As the author says in this article, it’s not their original idea, but this is the first time I’m hearing about it.
It basically boils down to play a game from your backlog for a bit, and whether you liked it or not, or kept playing it or bounced right off, you now have permission to remove it from your backlog. It sounds very freeing.
I take perhaps a little too much pride in having a very small catalogue of unplayed games (not because I play games a lot, but because I am dreadfully cheap and hardly ever buy anything lol), but even an old miser like me could probably benefit from a little tidying.
Just to echo the other comments about bundles, look at Humble Bundle right now, choice is $15 and has Persona 5 Royal and 8 other games, and P5R’s historical low is $20. I think some of the other games on the bundle are cool too, but I’m probably not going to play most of them right away, of at all. Likewise for Fanatical build your own bundles, sometimes one or two games makes the bundle worth it.
And there’s also free games from EGS and occasionally GOG and other stores. I haven’t spent a penny at EGS, yet I have hundreds of games and have finished maybe 3.
I only buy a game when I want to play it soon (next month or so), but sometimes it’s cheaper to get a bundle than just that game. I don’t spend a ton on games, but I have a ton.
