Not anymore, no. I used to beat games I deemed below average. But nowadays I'm more likely to drop a masterpiece than force myself to finish a "decent" game.
I dropped Ys 8, Valkyria Chronicles, Tears of the Kingdom, and... wait for it... Sekiro!! One of my GOAT games! I dropped them all close to the end.
Reason I dropped Sekiro is unique though. I got really sick for over a month, by the time I recovered I forgot so much and my immersion was killed. Dropped the other games because they started to bore me so I thought I needed a small break. But then the same thing happened... Immersion = slaughtered.
