I use a software called Collectorz to organize my stuff. Here’s a link to my video game backlog: https://cloud.collectorz.com/elsoragigante/games.
You’ll notice there’s less than the aforementioned 1500 games in my collection. There’s still a handful of games I haven’t bought yet that I want. That’s the Wishlist. I’ll have all those soon enough and make my journey that much more difficult.
