This tradition has continued. However, most games today are too big for me to truly find everything in them. Many games include a completion percentage that I tend to use, even if I know that 100% does not necessarily mean that I've found everything--especially in open world games. Sometimes, I set goals for myself based on what I learn about the game. As I have been busier these past few years, I'm usually content to simply get to the game's ending credits.
Many game systems now include special trophies that have a separate (harder to reach) percentage of completion. I do not believe that I have reached 100% for any of my games with those kinds of trophies--until today. The Spider-Man: Miles Morales game was short enough, and its trophies reasonable enough, that I finished a new game plus playthrough today to win the final few trophies that I did not earn on my original playthrough. Honestly, it was worth doing just to play through the story again.
It was nice to play a game to full completion again--not just beating the game, but finding all (or most) of the extra goodies.
