I tend to trade my games on console a lot of the time. Not all the time, there's stuff I do keep, but games like God of War: Ragnarok, or Last of Us 2, or a lot of the more story driven big games, I tend to trade those in for something else as I'm unlikely to replay them. Usually helps keep my console game costs down abit when I chain trade-ins. I think recently I went from God of War: Ragnarok, to trading for Sonic Forces (Didn't like), and then traded that towards Horizon: Forbidden West (Struggled to muster up interest in it to get to the meat of hte game), and now that was put towards my Metroid Prime Remastered or Zelda: Tears of the Kingdom pre-order, I forget which exactly, of which I'll be keeping both probably after I beat them.
Usually I want to keep game collection stuff, games that have really good replay value, or games I really loved.
